The document provides an overview of loops in C programming, explaining their purpose and types, including for loops, while loops, and do-while loops. It offers syntax examples and demonstrates how each type of loop operates in code. The conclusion highlights the importance of loops in writing efficient and readable code.

3. INTRODUCTION
For Example, You want to print your name i.e. Rahul, 5
times then here is a simple program to do the same.
#include<stdio.h>
#include<conio.h>
void main() {
printf(“Rahul”);
printf(“Rahul”);
printf(“Rahul”);
printf(“Rahul”);
printf(“Rahul”);
}

4. What is a loop
A loop statement allows us to execute a statement or a group of
statements multiple times based on a condition.
Loop statements are used to repeat the execution of statement or blocks.

5. Types of Loops in C
●For loop
●While loop
●Do while loop

6. For Loop
For loop is used to iterate the statements or a part of the program several times.
Syntax:-
for(variable initialize; condition; increment/decrement)
{
statement
}
Example:-
int main()
{ OUTPUT:- value is =
int i; 1
for(i=1; i<=3; i++) 2
{ 3
printf(“value is =%dn”, i);
}
}

7. While Loop
It is an entry control loop, so condition is tested before each iteration to decide whether to
continue or terminate the loop.
Syntax:-
Variable initialize;
While(condition)
{
Statement;
Increment/decrement;
}
Example:- OUTPUT:-
int main() { 1
int i; 2
i=1; 3
while(i<=3)
{ printf(“%dn”, i);
i++; }
}

8. Do while Loop
It is an exit control loop, condition is checked after one time execution of the body of the loop.
Syntax:-
Variable initialize;
do {
Statement;
Increment/Decrement; }
while(condition);
Example:- OUTPUT:- value is =
int main() { 1
int i; 2
i=1; 3
do {
printf(“ value is = %dn”, i);
i++; }
while(i<=3);
}

9. CONCLUSIONS
loops are very important in any
programming language as they
allow us to reduce the number
of lines in a code, making our
code more readable and
efficient.
