Switch statements and looping statements are key programming concepts. Switch statements allow a program to evaluate an expression and branch to different blocks of code based on the resulting value. Common switch statements include if/else. Looping statements let a program repeat blocks of code a specified number of times or while a condition remains true. Common looping statements include while, do/while, and for loops. Together, switch and looping statements allow programs to selectively execute code and repeat tasks as needed to process inputs and achieve the desired output.
The document discusses looping statements in programming which allow a block of code to be repeatedly executed until a certain condition is reached. There are three main types of loops: for loops, while loops, and do-while loops. For loops initialize a variable, specify a condition, and update the variable each iteration. While loops continuously execute the code block as long as the condition is true. Do-while loops are similar to while loops but execute the code block at least once even if the condition is false.
The document discusses programming concepts including switch case statements, looping, and different types of loops like for, while, and do-while loops. It provides examples of how to write switch case statements to select different code blocks based on a variable's value. It also explains the different parts of for, while, and do-while loops and provides examples of each type of loop. Several short programs are included that demonstrate using loops and switch case statements to process user input and perform calculations.
The document discusses PHP control structures and operators including switch-case statements, while loops, do-while loops, and for loops. The switch-case statement allows executing different code blocks based on different conditions. While and do-while loops repeat a block of code as long as or until a condition is true. The for loop is used when the number of iterations is known and repeats code a specific number of times.
The document discusses programming languages and different types of loops in programming. It provides examples of for, while, and do-while loops. A for loop initializes a variable, specifies a condition, and updates the variable on each iteration. A while loop runs code while a condition is true. A do-while loop runs code once then checks the condition on subsequent iterations. Loops allow code to repeat to produce greater results through repetition.

Here is an example of a basic for loop in C++:
for (int i = 0; i < 10; i++) {
cout << i << endl;
}
This loop will print the numbers 0 through 9. It initializes the variable i to 0, checks that i is less than 10 for the condition, and increments i by 1 each iteration via i++.
Final requirement in programming vinsonmonstergeorge
Here are the key steps in a for loop:
1. Initialize a counter variable (often i) to track the number of iterations
2. Define a condition to check on each iteration (often i < 10)
3. Increment/decrement the counter variable after each iteration (often i++)
4. The code block inside the for loop will repeat until the condition is no longer true
So in summary, a for loop allows you to repeat a block of code a specific number of times by initializing/updating a counter variable and checking its value on each iteration.
Scripts are programs or sequences of instructions that are interpreted by another program rather than directly by the processor. Popular scripting languages include JavaScript, Perl, and VBScript. JavaScript scripts can be used to create dynamic web pages and validate form data. To include JavaScript in an HTML document, the <script> tag is used with type="text/javascript". Variables are containers that store information in JavaScript and can be assigned values using operators like =, +, -, *, /, etc.

The document discusses programming languages and different types of loops used in programming. It defines programming as using a computer language to develop applications and scripts for a computer to execute. It then describes the different types of loops - for loops, which allow initialization of a variable, checking a condition, and updating the variable; while loops, which repeat code while a condition is true; and do-while loops, which execute code at least once before checking the condition. Examples of each loop type are provided to illustrate their usage.
Switch case statements provide an alternative to long if/else statements when comparing a variable to multiple integral values. The basic format compares the variable to case values, executing code for a matching case. A default case handles non-matching values. Loops allow code to repeat, with for, while, and do-while loops. For loops initialize/update a variable and check a condition each repetition. While loops check a condition and repeat until it's false. Loops are useful for repeating tasks like displaying lists of data.
Programming involves using computer languages to develop applications, scripts, or other instructions for computers. It is a creative process where programmers instruct computers on tasks through programming languages.

One example shows a do-while loop that displays a menu to the user and waits for a valid selection. The variable used in the loop condition must be declared outside the do block to be accessible after the block executes.
Fundamentals of programming final santosAbie Santos
This document discusses programming concepts like switch case statements, looping statements, and if-else statements. It provides examples of code and explanations of how to write and run different statements in C++. It also includes links to external websites that contain additional examples of programming concepts and how they appear when compiled and executed.
Switch case and looping statements are programming constructs that allow for conditional execution of code blocks. A switch case statement allows a variable's value to control program flow via multiple branches, improving clarity over long if statements. Looping statements like while and for loops execute a block of code repeatedly, allowing programs to perform repetitive tasks or process collections of data by running the same code multiple times. These programming structures are essential for many applications to make complex decisions and process large amounts of information.
Programming involves instructing a computer using a programming language. It allows organizing ideas about processes and things. Programming languages let programmers develop applications and scripts for computers to execute. Programming involves understanding codes, program development, and applications like web browsers. Switch cases and looping systems are important programming concepts. Switch cases allow selecting different code blocks based on a variable. Common looping structures include for, while, do-while, and foreach loops, which repeat a block of code a specified number of times. Programming requires attention to syntax and careful coding to avoid errors.

2. Programming
We first define the word “programming”, it is a computer
language programmers use to develop applications, scripts,
or other set of instructions for a computer to execute.
Programming is instructing a computer to do something for
you with the help of a programming language. The role of
a programming language can be described in two ways:
Technical: It is a means for instructing a Computer to
perform Tasks
Conceptual: It is a framework within which we organize
our ideas about things and processes.

3. A programming language should
both provide means to describe
primitive data and procedures and
means to combine and abstract those
into more complex ones.
http://eglobiotraining.com/
4. The distinction between data and procedures is
not that clear cut. In many programming languages,
procedures can be passed as data (to be applied to ``real''
data) and sometimes processed like ``ordinary'' data.
Conversely ``ordinary'' data can be turned into
procedures by an evaluation mechanism.

5. If we know how to write a C expression that is
equivalent of a question such as “Is resting the value
of expression to select a course of action. In C, the
statement is the primary selection control structure
A programming language is an artificial language
designed to communicate instructions to a machine,
particularly a computer. Programming languages can
be used to create programs that control the behavior
of a machine and/or to express algorithms precisely.

6. At first, programming is confusing because you have so
much to understand about codes that will enable to run a
program. Programming has applications and program
development, the best example for this is the Internet
browser…
Programming is a creative process done by
programmers to instruct a computer on how to do a task.
Programming languages let you use them in different
ways, e.g adding numbers, etc… or storing data on disk
for later retrieval.

7. You have to consider languages to run or write your
own program, most demanded language in programming is
the DEV C++ (a full-featured Integrated Development
Environment (IDE)).
C++ is one of the most used programming languages
in the world. Also known as "C with Classes".
New to programming or thinking about it? It might surprise
you to know that there are many programmers who program
just for fun and it can lead to a job.

9. - A switch, case, select or inspect statement is a type of selection
control mechanism that exists in most imperative programming
languages such as Pascal, Ada, C/C++, C#, Java, and so on. It is
also included in several other types of languages. Its purpose is to
allow the value of a variable or expression to control the flow of
program execution via a multiway branch (or "goto", one of
several labels).
The Main Reason using switch case :
- To improve clarity, by reducing otherwise repetitive coding, and (if
the heuristics permit) also offering the potential for faster execution
through easier compiler optimization in many cases.
http://eglobiotraining.com/
10. PROGRAMS THAT IS RELATED TO SWITCH CASE
1. The If – else Statement
-The if statement allows the programmer to make
decisions within a program.
- The general format of an if statement is:
If (expression)
statement
-Where expression represents a relational, equality, or
logical expression ( conditional expression) .
http://eglobiotraining.com/
11. If statement (two alternatives)
Form:
If (condition) Note: if condition evaluates to true, then statement is
statement; executed and statement is skipped; otherwise, statement is
else skipped and statement is executed
statement;
If statement (One-Alternatives)
Form:
If (condition) Note: if condition evaluates to true, then statement is
statement; executed and statement is skipped
Format of the if statement
- All if statement examples in this text indent statements. The word else
Is typed without indention on a separate line. The format of the if statement
makes its meaning apparent and is used solely to improve program readability;
The format makes no difference to the computer

12. There may be a situation when you need to execute a block
of code several number of times. In general statements are
executed sequentially: The first statement in a function is
executed first, followed by the second, and so on.
Programming languages provide various control structures
that allow for more complicated execution paths.
A loop statement allows us to execute a statement or group
of statements multiple times and following is the general
from of a loop statement in most of the programming
languages:

29. #include <iostream>
using namespace std;
int main ()
{
int selector;
cout << "Please select one of the folloeing games:n" << "nl. Guildwarsn" << "2. World of the Warcraftn"
<< "3. Half Life 2n" << endl;
cout << "Please fill in the number of the game: ";
cin >> selector;
switch(selector)
{
case 1:
system("CLS");
cout << "Name: Guildwarsn" << "Company: ArenaNetn" << endl;
break;
case 2:
system("CLS");
cout << "Name: World of Warcraftn" << "Company: Blizzardsn" << endl;
break;
case 3:
sytem("CLS");
cout << "Name: Half Life 2n" << "Company: Valven" << endl;
} break;
system("PAUSE");
}

34. #include <iostream>
using namespace std;
int main ()
{
char permit;
cout << "Are you sure you want to quit? (y/n) : ";
cin >> permit;
switch (permit)
{
case 'y' :
cout << "Hope to see you again!n";
break;
case 'n' :
cout << "Welcome back!n" ;
break;
default:
cout << "What? I don't get it!n";
}
return 0;
}

39. Looping Statements
- Loops execute a block of code a specified number of
times, or while a specified condition is true.
- in PHP, the following looping statements are used:
*The while Loop
* The Do… While Loop
* The For Loop
*The Foreach Loop
*Break and continue statement
http://eglobiotraining.com/
40. While structure is another type of loop statements,
where the condition is checked at first, the iteration
will not stop even if the value changes while executing
statements.
Form:
While(condition)
{
code to be executed;
}
http://eglobiotraining.com/
41. Do while statement is same as the while
statement , the only difference is that it evaluates
the expression at the end.
Form:
do
{
code to be executed;
}
while (condition):
42. The for loop is used when you know in advance how
many times the script should run.
Be for statement takes three expressions inside its
parentheses separated by semi-colons. When the for
loop executes, the following occurs:
The initializing expression is executed. This
expression usually initializes one or more loop
counter, but the syntax allow expression any degree of
complexity.
The condition expression is evaluated. Of the value of
condition is true, the loop statements execute. If the
value of condition is false, the for loop terminates.
http://eglobiotraining.com/
44. For Each structure is a loop structure used for
arrays
Form:
foreach(array as value)
{
code to be executed
}
Foreach (array as key => value)
{
code to be executed
}
http://eglobiotraining.com/
45. Break ends the execution of the for, for
each, while, do-while or switch statement.
Form:
* Break ( optional numeric argument)
http://eglobiotraining.com/
46. “Continue” is used to skip the current loop iteration and
continue with the next iteration of the loop. But “Break” is to
exit from the whole loop.
Form:
* Break ( optional numeric argument)

57. #include <iostream>
using namespace std;
int main()
{
int x;
x = 1;
cout<<"THIS IS 5x Printed the Hello, world!n";
do {
cout<<"Hello, world!n";
x++;
} while ( x <= 5 );
cin.get();
}

61. #include<iostream.h>
#define c cout
main(){
c<<"THIS IS AN EXAMPLE OF INCREMENT LOOPINGn";
for(int z=1;z<=5;z++){
c<<z;
c<<"n";
}
system("pause");
return 0;
