The chapters in this book are structured in a pedagogical sequence, which makes this textbook very effective in learning the features and capabilities of the software.
There are three primary data types in C - char, int, and float. Programmers can derive many other data types from these. For integers, C offers short and long types which occupy 2 and 4 bytes respectively and have different value ranges. Integers can also be declared as signed or unsigned, changing whether negative values are allowed. Char values can also be signed or unsigned, affecting their range from -128 to 127 or 0 to 255. Floating point types include float, double, and long double with increasing range and memory usage.
Block coding replaces groups of m bits with groups of n bits, where n is greater than m, adding redundancy. It is applied before line coding to improve the performance of line coding. Specifically, 4B/5B block coding replaces each 4-bit block with a 5-bit block, using the extra bit for control or signaling. The process involves dividing the bit sequence into m-bit groups, substituting each m-bit group with an n-bit group, and combining the n-bit groups into an output stream.
This document provides an overview of data types in C programming, including:
1) It describes four main types of data types - fundamental, modifiers, derived, and user defined. Fundamental types include integer, character, float, void. Modifiers change properties of other types. Derived types include arrays and pointers.
2) It explains the integer, float, character, and void fundamental data types in more detail. Integer can be short, int, long. Float and double store numbers in mantissa and exponent. Character represents keyboard characters.
3) Common C data type sizes and value ranges are provided for integer, float, and character types along with their modifiers like short, long, signed, unsigned.
Huffman coding is a lossless data compression technique that converts fixed length codes to variable length codes. It assigns shorter codes to more frequent characters and longer codes to less frequent characters. This allows for more efficient data storage and transmission. The key steps are to create a frequency table of characters, construct a binary tree based on frequencies, and extract the Huffman codes from the tree. Huffman coding can significantly reduce file sizes by achieving better compression than fixed length codes. It is used widely in file formats like ZIP, JPEG, and MPEG.

In VB.Net, TextBox and RichTextBox are two different tools.This presentation will explain some of the events, properties and methods of TextBox and RichTextBox of VB.Net in simple language for the beginners
- The toString() method in Object provides a default implementation but it does not generally provide useful output for custom classes.
- Classes should override toString() to provide a concise but informative string representation of the object in a human-readable format.
- This makes objects more pleasant to use with operations like println and string concatenation which implicitly call toString().
The document discusses error detection and correction techniques. It introduces Hamming codes, which can detect up to two bit errors and correct one bit errors. It explains how Hamming codes work by adding redundant parity bits to messages based on the values of data bits. A 4x7 generator matrix is used to encode 4-bit data words into 7-bit codewords for the Hamming(7,4) code. An example shows how a data word of 1010 encodes to the codeword 1011010. The summary then tests a C++ implementation of Hamming code encoding.
In the world of technology is already integrated into the network must have a data transmission process. Sending and receiving data communications systems do not avoid mistakes. Packets of data sent from the server to the client computer always have an error in transmission. These shipments have leaks that occur due to changes in voltage, frequency or impact. One of the methods used to detect and correct errors in data transmission is the Hamming method. This method will check bit errors in delivery. Hamming is to do the process at fault detection, and then the error will be corrected so that the arrangement of the bits will go back to the bit sequence before the data is sent. With the application of this method, the data transmission process will avoid mistakes. Data will be saved to the destination.

The document discusses different types of addressing modes used in computer instructions. There are 7 main addressing modes: immediate, direct, indirect, register, register indirect, displacement, and stack. Immediate addressing encodes the operand value directly in the instruction. Direct addressing specifies the memory address of the operand. Indirect addressing uses the value at an address as the address of the operand. Register addressing uses a register value as the operand address.
This document discusses data types, variables, and constants in programming. It explains that variables must be declared with a name and data type. The basic data types covered are date, string, boolean, decimal, short, integer, single, and double. It provides the ranges and storage sizes for each data type. The document also discusses naming conventions for variables using prefixes related to data type. Constants are described as values that do not change while a program runs.
While doing programming in any programming language, you need to use various variables to store various information. Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory.
You may like to store information of various data types like character, wide character, integer, floating point, double floating point, boolean etc. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory.
Strings in C can be declared as character arrays that are terminated with a null character '\0'. Strings can be initialized by assigning character constants in quotes or curly braces. Common string library functions allow input of strings with scanf and gets, getting the length with strlen, concatenating with strcat, comparing with strcmp, and copying with strcpy.
Scope and extent refer to the region and duration in which references to objects can occur in Common Lisp. The scope is determined by factors like the location of the reference, the expression type, and location in the program text. There are different types of scope including lexical scope, where references are only allowed in certain program portions, indefinite scope with anywhere references, and dynamic extent where references are allowed between establishment and disestablishment. Scope and extent are important concepts for understanding variable bindings and references in Common Lisp.

Constants Variables Datatypes by Mrs. Sowmya JyothiSowmyaJyothi3
C provides various data types to store different types of data. The main data types are integer, float, double, and char. Variables are used to store and manipulate data in a program. Variables must be declared before use, specifying the data type. Constants are fixed values that don't change, and can be numeric, character, or string values. Symbolic constants can be defined to represent constant values used throughout a program. Input and output of data can be done using functions like scanf and printf.
The document describes intermediate code generation during compilation.
1) An intermediate language is used to translate source programs into a form that is CPU independent yet close to machine language. This facilitates code optimization and retargeting of compilers.
2) Common intermediate languages include syntax trees, postfix notation, and three-address code using quadruples. Three-address code breaks down expressions into single assignment statements to simplify optimization.
3) Semantic rules for syntax-directed translation are described to generate three-address code for expressions, assignments, procedures, and other language constructs. Attributes track temporary variables and generated code.

6. Naming Rules for
Variable and Constant
Prepared by: Mr Pork Naron
Can be letters, digits, and the underscore,
but must begin with a letter
cannot contain spaces or periods
cannot be VB reserved words such as LET,
PRINT, DIM, or CONST
are not case sensitive. This means that
TotalInteger, TOTALINTEGER, and
totalinteger are all equivalent names
7. Naming Convention
Prepared by: Mr Pork Naron
Create meaningful names
Avoid using abbreviations
Begin each name with an uppercase letter and
capitalize each successive word in the name.
Use mixed case (such as AmountDueDecimal) for
variables – use Uppercase for constant names
(such as TAX_RATE_SINGLE)
8. Declaring Variable & Constant
Prepared by: Mr Pork Naron
Variable
Dim
Eg: Dim EmployeeName as String
Constant
Const
Eg: Const Age as Integer=23
9. Scope of Variables and Constants
Prepared by: Mr Pork Naron
Namespace : Public Shared(visible in whole
project)
Module level: Private(variable), Const (
constant) – visile any procedure in specific form.
Local : Dim(variable), Const (constant) visible
in only one procedure
Block : Dim(variable), Const(constant) – visible
in only a portion of procedure
10. Converting Input Data Types
Prepared by: Mr Pork Naron
Text property – always stores string
values, even if the string looks like a
number.
Parse method – converts a value from
a Text property to an equivalent
numeric value or other types
11. Converting Variable Values to Output
Data Types
Prepared by: Mr Pork Naron
Use (.ToString) method to convert
variable value to output data
TxtOutput.text = Output.ToString()
Create meaningful names – do not name a variable or constant X or Y or XInteger.
Instead use names such as StudentNameString, CountStudentsInteger, and
AmountDueDecimal.
2. Avoid using abbreviations unless the abbreviation is standard and well-accepted such as
SSNString for storing social security number values.
3. Begin each name with an uppercase letter and capitalize each successive word in the
name.
4. Use mixed case (such as AmountDueDecimal) for variables – use Uppercase for
constant names (such as TAX_RATE_SINGLE).
As part of the Input phase of the Input-Process-Output model, you must convert values from
the Text property of a TextBox and store the converted values to memory variables.
Text property – always stores string values, even if the string looks like a number.
Parse method – converts a value from a Text property to an equivalent numeric value for storage to a numeric variable. Parse means to examine a string character by character and convert the value to another format such as decimal or integer.. In order to parse a string that contains special characters such as a decimal point, comma, or currency symbol, use the Globalization enumeration shown in the coding examples below.
§ If you don’t specify the Globalization value of Globalization.NumberStyles.Currency, then a value entered into a textbox controlsuch as $1,515.95 will NOT parse to Decimal.
The Globalization value Globalization.NumberStyles.Number will allow the Integer.Parse method to parse a textbox value that contains a comma, such as 1,249.
VB's Intellisense will display the various possible values for the Globalization enumeration.
Example #1 – this example shows you how to declare numeric variables then store values to them from Textbox controls.
-----------------Declare variables------------------
Dim PriceDecimal As Decimal
Dim QuantityInteger As Integer
---------------Convert values from textbox controls to memory
PriceDecimal = Decimal.Parse(PriceTextBox.Text,Globalization.NumberStyles.Currency)
QuantityInteger = Integer.Parse(QuantityTextBox.Text,Globalization.NumberStyles.Number)
Example #2 – this example shows you how to declare numeric variables and store values to them from Textbox controls using a single assignment statement in one step.
----------------------Declare variables and convert values from textbox controls to memory in a single statement
Dim PriceDecimal As Decimal = Decimal.Parse(PriceTextBox.Text, Globalization.NumberStyles.Currency)
Dim QuantityInteger As Integer = Integer.Parse(QuantityTextBox.Text, Globalization.NumberStyles.Number)
Older versions of VB used named functions to convert values. Examples are the CDec
(convert to Decimal) and CInt (convert to Integer) functions shown here – you may encounter
these functions in other VB books that you read or in the VB Help files.
There are some advantages to these named functions:
· A TextBox Text property value of $100.00 will NOT generate an error if you use the CDec
function to convert the value as shown below—the data will convert satisfactorily.
· The functions are faster and easier to type.

PriceDecimal = CDec(PriceTextBox.Text)
QuantityInteger = CInt(QuantityTextBox.Text)
In order to display numeric variable values as output the values must be converted from
numeric data types to string in order to store the data to the Text property of a TextBox control.
Use the ToString method. These examples show converting strings to a numeric
representation with 2 digits to the right of the decimal (N2) and currency with 2 digits to the right
of the decimal (C2) as well as no digits to the right of a number (N0 – that is N zero, not N
Oh).

The order of precedence for expressions that have more than one operation is the same as
for other programming languages.
The order of precedence is applied to an expression by evaluating the expression from left to
right for values within parentheses – within parentheses VB will process the expression from left
to right looking for an applying the exponentiation operator, then again from left to right applying
the multiplication and division operators, etc. This left to right application of operators continues
in pass-after-pass working down the order of precedence.
Use parentheses to control the application of the order of precedence of operations.
· Example #1: (5 + 6) * 2 is evaluated:
first as 5 + 6 = 11, because the parentheses force the addition operation to be evaluated before the multiplication operation, or next VB will multiple 11 by 2 to arrive at 22.
· Example #2: 5 + 6 * 2 is evaluated:
first as 6 * 2 = 12, because the multiplication operator is higher in the order of precedence, o next VB will add 5 to 12 to arrive at 17.
