The document discusses two types of type casting in Java - implicit and explicit. Implicit type casting is performed by the compiler and involves widening or upcasting from a lower to higher datatype without loss of information. Explicit type casting requires a programmer and involves narrowing or downcasting which can result in loss of information as higher order bits are truncated. Examples are provided to illustrate implicit type casting between char to int and int to double, as well as explicit casting from int to byte which results in truncation of higher order bits.
Operators are elements in C# that are applied to operands in expressions or statements. Unary operators take one operand, like increment (++), while binary operators take two operands, such as arithmetic operators (+, -, *, /). The conditional operator (?:) is the sole ternary operator, taking three operands. Some common operators are assignment (=), arithmetic, comparison, conditional (&&, ||), ternary (?:), and null coalescing (??). Operator precedence and associativity determine the order of evaluation in expressions with multiple operators. Parentheses can be used to override precedence.

operators
2. Implementing Sentinel-Controlled
Repetition in Class GradeBook
• In this version of the program we show class GradeBook containing
member function determineClassAverage that implements the
pseudocode algorithm
• Although each grade entered is an integer, the averaging calculation
is likely to produce a number with a decimal point—in other words,
a real number or floating-point number (e.g., 7.33, 0.0975 or 1000.12345).
• The type int cannot represent such a number, so this class must use another type
to do so.
• C++ provides several data types for storing floating-point numbers in memory,
including float and double. The primary difference between these types is that,
compared to float variables, double variables can typically store numbers with
larger magnitude and finer detail (i.e., more digits to the right of the decimal
point—also known as the number’s precision).
• This program introduces a special operator called a cast operator to force the
averaging calculation to produce a floating-point numeric result.

4. Software Engineering Tips!
• Omitting the braces that delimit a block can lead to logic
errors, such as infinite loops. To prevent this problem, some
programmers enclose the body of every control statement in
braces, even if the body contains only a single statement.
• Using floating-point numbers in a manner that assumes
they’re represented exactly (e.g., using them in comparisons
for equality) can lead to incorrect results. Floating-point
numbers are represented only approximately.
5. Floating-Point Number Precision and
Memory Requirements
• Variables of type float represent single-precision floating-point
numbers and have approximately seven significant digits on most
32-bit systems.
• Variables of type double represent double-precision floating-point numbers. These
require twice as much memory as float variables and provide approximately 15
significant digits on most 32-bit systems—approximately double the precision of
float variables.
• Most programmers represent floating-point numbers with type double. In fact,
C++ treats all floating-point numbers you type in a program’s source code (such as
7.33 and 0.0975) as double values by default. Such values in the source code are
known as floating-point constants.
• In conventional arithmetic, floating-point numbers often arise as a result of
division—10 divided by 3, the result is 3.3333333…. The computer allocates only a
fixed amount of space to hold such a value, so clearly the stored floating-point
value can be only an approximation. Image Credit: raymondclarkeimages
6. Floating-Point Number Precision and
Memory Requirements
• Although floating-point numbers are not always 100 percent precise, they have
numerous applications.
• For example, when we speak of a “normal” body temperature of 98.6, we do not
need to be precise to a large number of digits. When we read the temperature on
a thermometer as 98.6, it may actually be 98.5999473210643.
• Calling this number simply 98.6 is fine for most applications involving body
temperatures.
• Due to the imprecise nature of floating-point numbers, type double is preferred
over type float, because double variables can represent floating-point numbers
more accurately. For this reason, we will type double throughout our code
examples.

7. Converting Between Fundamental
Types Explicitly and Implicitly
• In our code, the variable average is declared to be of type double to capture the
fractional result of our calculation.
• However, total and gradeCounter are both integer variables.
• Recall that dividing two integers results in integer division, in which any fractional
part of the calculation is lost truncated).
• In the following statement:
• the division occurs first—the result’s fractional part is lost before it’s assigned to
average.
average = total / gradeCounter;
Image Credit: www.fastbooking.com
8. Converting Between Fundamental
Types Explicitly and Implicitly
• To perform a floating-point calculation with integers, we must create temporary
floatingpoint values.
• C++ provides the unary cast operator to accomplish this task.
• We use the cast operator static_cast<double>(total) to create a temporary
floating-point copy of its operand in parentheses—total.
• Using a cast operator in this manner is called explicit conversion. The value stored
in total is still an integer.
• The calculation now consists of a floating-point value (the temporary double
version of total) divided by the integer gradeCounter.

9. Converting Between Fundamental
Types Explicitly and Implicitly
• The compiler knows how to evaluate only expressions in which the operand types
are identical. To ensure that the operands are of the same type, the compiler
performs an operation called promotion (also called implicit conversion) on
selected operands.
• For example, in an expression containing values of data types int and double, C++
promotes int operands to double values.
• In our example, we are treating total as a double (by using the unary cast
operator), so the compiler promotes gradeCounter to double, allowing the
calculation to be performed—the result of the floating-point division is assigned to
average.
Image Credit: www.thinkwithgoogle.com
10. Converting Between Fundamental
Types Explicitly and Implicitly
• Cast operators are available for use with every data type and with class types as
well.
• The static_cast operator is formed by following keyword static_cast with angle
brackets (< and >) around a data-type name. The cast operator is a unary
operator—an operator that takes only one operand.
• Cast operators have higher precedence than other unary operators, such as unary
+ and unary -. This precedence is higher than that of the multiplicative operators *,
/ and %, and lower than that of parentheses.

11. Formatting for
Floating-Point Numbers
• The call to setprecision in our program (with an argument of 2) indicates that
double variable average should be printed with two digits of precision to the right
of the decimal point (e.g., 92.37).
• This call is referred to as a parameterized stream manipulator
(because of the 2 in parentheses).
• Programs that use these calls must contain the preprocessor directive:
• The manipulator endl is a nonparameterized stream manipulator (because it isn’t
followed by a value or expression in parentheses) and does not require the
<iomanip> header.
• If the precision is not specified, floating-point values are normally output with six
digits of precision (i.e., the default precision on most 32-bit systems today).
#include <iomanip>
Image Credit: www.ebay.com
12. Formatting for
Floating-Point Numbers
• The stream manipulator fixed indicates that floating-point values should be
output in so-called fixed-point format, as opposed to scientific notation.
• Scientific notation is a way of displaying a number as a floating-point number
between the values of 1.0 and 10.0, multiplied by a power of 10.
• For instance, the value 3,100.0 would be displayed in scientific notation as
3.1 × 103. Scientific notation is useful when displaying values that are very large or
very small.
• Fixed-point formatting, on the other hand, is used to force a floating-point
number to display a specific number of digits. Specifying fixed-point formatting
also forces the decimal point and trailing zeros to print, even if the value is a whole
number amount, such as 88.00.
• Without the fixed-point formatting option, such a value prints in C++ as 88 without
the trailing zeros and without the decimal point.
Image Credit: www.vectorstock.com
13. Formatting for
Floating-Point Numbers
• When the stream manipulators fixed and setprecision are used in a program, the
printed value is rounded to the number of decimal positions indicated by the value
passed to setprecision (e.g., the value 2 in our program), although the value in
memory remains unaltered. |
• For example, the values 87.946 and 67.543 are output as 87.95 and 67.54,
respectively.
• It’s also possible to force a decimal point to appear by using stream manipulator
showpoint. If showpoint is specified without fixed, then trailing zeros will not
print. Like endl, stream manipulators fixed and showpoint do not use parameters,
nor do they require the <iomanip> header.
• Both can be found in header <iostream>.
Image Credit: www.directindustry.com
14. Formatting for
Floating-Point Numbers
• The program outputs the class average rounded to the nearest hundredth and
with exactly two digits to the right of the decimal point.
• The parameterized stream manipulator indicates that variable average’s value
should be displayed with two digits of precision to the right of the decimal point—
indicated by setprecision( 2 ).
• The three grades entered during the sample execution of the program
in total 257, which yields the average 85.666666….

15. Formulating Algorithms:
Nested Control Statements
• For the next example, we once again formulate an algorithm by using pseudocode
and topdown, stepwise refinement, and write a corresponding C++ program.
• We’ve seen that control statements can be stacked on top of one another (in
sequence). Here, we examine the only other structured way control statements
can be connected, namely, by nesting one control statement within another.
Image Credit: www.thetelecomblog.com
16. Formulating Algorithms:
Nested Control Statements
• Consider the following problem statement:
A college offers a course that prepares students for the state licensing exam for real
estate brokers. Last year, ten of the students who completed this course took the exam.
The college wants to know how well its students did on the exam. You’ve been asked to
write a program to summarize the results. You’ve been given a list of these 10
students. Next to each name is written a 1 if the student passed the exam or a 2 if the
student failed.
• Your program should analyze the results of the exam as follows:
1. Input each test result (i.e., a 1 or a 2). Display the prompting message
“Enter result” each time the program requests another test result.
2. Count the number of test results of each type.
3. Display a summary of the test results indicating the number of
students who passed and the number who failed.
4. If more than eight students passed the exam, print the message
“Bonus to instructor!” Image Credit: german.yale.edu
17. Formulating Algorithms:
Nested Control Statements
After reading the problem statement carefully, we make the following observations:
1. The program must process test results for 10 students. A counter-controlled loop
can be used because the number of test results is known in advance.
2. Each test result is a number—either a 1 or a 2. Each time the program reads a test
result, the program must determine whether the number is a 1 or a 2. We test for
a 1 in our algorithm. If the number is not a 1, we assume that it’s a 2.
3. Two counters are used to keep track of the exam results—one to count the number
of students who passed the exam and one to count the number of students
who failed the exam.
4. After the program has processed all the results, it must decide whether more than
eight students passed the exam.

18. Formulating Algorithms:
Nested Control Statements
• Let’s proceed with top-down, stepwise refinement. We begin with a pseudocode
representation of the top:
• Once again, it’s important to emphasize that the top is a complete representation
of the program, but several refinements are likely to be needed before the
pseudocode evolves naturally into a C++ program.
• Our first refinement is:
Analyze exam results and decide whether a bonus should be paid
Initialize variables
Input the 10 exam results, and count passes and failures
Display a summary of the exam results and decide whether a bonus should be paid
Image Credit: fullcircleinsights.com
19. Formulating Algorithms:
Nested Control Statements
• Even though we have a complete representation of the entire program, further
refinement is necessary.
• We now commit to specific variables. Counters are needed to record the passes
and failures, a counter will be used to control the looping process and a variable is
needed to store the user input.
• The last variable is not initialized, because its value is read from the user during
each iteration of the loop.
• The pseudocode statement
• can be refined as follows:
Initialize variables
Initialize passes to zero
Initialize failures to zero
Initialize student counter to one
Image Credit: caladay.wordpress.com
20. Formulating Algorithms:
Nested Control Statements
• Notice that only the counters are initialized at the start of the algorithm.
• The pseudocode statement:
• requires a loop that successively inputs the result of each exam. Here it’s known in
advance that there are precisely 10 exam results, so counter-controlled looping is
appropriate.
• Inside the loop (i.e., nested within the loop), an if…else statement will determine
whether each exam result is a pass or a failure and will increment the appropriate
counter. The refinement of the preceding pseudocode statement is then:
Input the 10 exam results, and count passes and failures
While student counter is less than or equal to 10
Prompt the user to enter the next exam result
Input the next exam result
If the student passed
Add one to passes
Else
Add one to failures
Add one to student counter

21. Formulating Algorithms:
Nested Control Statements
• The pseudocode statement:
• can be refined as follows:
Display a summary of the exam results and decide whether a bonus should be paid
Display the number of passes

23. Conversion to Class Analysis
• Our next program implements the pseudocode.
• This example does not contain a class—it contains just
a source code file with function main performing all the
application’s work.
• This source code file contained function main, which created an object of the class
and called its member functions. Occasionally, when it does not make sense to try
to create a reusable class to demonstrate a concept, we’ll use an example
contained entirely within the main function of a single source code file.
• The program declares the variables used to process the examination results. We’ve
taken advantage of a feature of C++ that allows variable initialization to be
incorporated into declarations (passes is initialized to 0, failures is initialized to 0
and studentCounter is initialized to 1).
Image Credit: www.freshideawebsites.com2
24. Conversion to Class Analysis
• The while statement in the program loops 10 times. Each iteration inputs and
processes one exam result.
• The if…else statement for processing each result is nested in the while statement.
If the result is 1, the if…else statement increments passes; otherwise, it assumes
the result is 2 and increments failures.
• The program increments studentCounter before the loop condition is tested again.
After 10 values have been input, the loop terminates and the program displays the
number of passes and the number of failures.
• The if statement in determines whether more than eight students passed the
exam and, if so, outputs the message "Bonus to instructor!".

26. Assignment Operators
• C++ provides several assignment operators for
abbreviating assignment expressions.
• For example, the statement:
can be abbreviated with the addition assignment operator += as:
which adds the value of the expression on the operator’s right to the value of the
variable on the operator’s left and stores the result in the left-side variable.
c = c + 3;
c += 3;
Image Credit: www.wpclipart.com
27. Assignment Operators
• Any statement of the form:
in which the same variable appears on both sides of the assignment operator and
operator is one of the binary operators +, -, *, /, or %, can be written in the form:
variable = variable operator expression;
variable operator= expression;
28. Increment and Decrement
Operators
• In addition to the arithmetic assignment operators,
C++ also provides two unary operators for adding 1 to
or subtracting 1 from the value of a numeric variable.
• These are the unary increment operator, ++, and the unary decrement operator, --.
• A program can increment by 1 the value of a variable called c using the increment
operator, ++, rather than the expression c = c + 1 or c += 1.
• An increment or decrement operator that’s prefixed to (placed before) a variable is
referred to as the prefix increment or prefix decrement operator, respectively.
• An increment or decrement operator that’s postfixed to (placed after) a variable is
referred to as the postfix increment or postfix decrement operator, respectively.
Image Credit: www.property118.com
29. Software Engineering Tips!
• Unlike binary operators, the unary increment and decrement
operators should be placed next to their operands, with no
intervening spaces.
• Attempting to use the increment or decrement operator on an
expression other than a modifiable variable name or
reference, e.g., writing ++(x + 1), is a syntax error.
32. What We Covered Today
1. We used control-statement stacking to total
and compute the average of a set of student
grades with counter- and sentinel-controlled
repetition, and we used control statement
nesting to analyze and make decisions based
on a set of exam results.
2. We introduced assignment operators, which
can be used for abbreviating statements. We
presented the increment and decrement
operators, which can be used to add or
subtract the value 1 from a variable.

37. How To Make Really, Really Long
IF Statements: Logical Operators
• The operator ! is the C++ operator for the Boolean operation NOT. It has only one
operand, to its right, and inverts it, producing false if its operand is true, and true if
its operand is false. Basically, it returns the opposite Boolean value of evaluating its
operand.
• The logical operators && and || are used when evaluating
two expressions to obtain a single relational result.
• The operator && corresponds to the Boolean logical operation AND, which yields
true if both its operands are true, and false otherwise.
• The operator || corresponds to the Boolean logical operation OR, which yields
true if either of its operands is true, thus being false only when both operands are
false.
• When using the logical operators, C++ only evaluates what is necessary from left to
right to come up with the combined relational result, ignoring the rest. This is
known as short-circuit evaluation Image Credit: www.linkedin.com
39. Today’s In-Class C++
Programming Assignment
• Develop a C++ program that will
determine if a department store
customer has exceeded the credit
limit on a charge account. For
each customer, the following
facts are available:
a) Account number (an integer)
b) Balance at the beginning of the month
c) Total of all items charged by this
customer this month
d) Total of all credits applied to this
customer's account this month
e) Allowed credit limit
• The program should input each of
these facts, calculate the new
balance (= beginning balance +
charges – credits) and determine
if the new balance exceeds the
customer's credit limit. For those
customers whose credit limit is
exceeded, the program should
display the customer's account
number, credit limit, new balance
and the message “Credit limit
exceeded”.
