7.Loop Statement in C Programming l C Tutorials for beginers#7 

Loop in c

ans: Loop can execute a statement multiple times.

Types of Loop

1-for loop

2-while loop

3.Do-while loop

For Loop in c

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

Syntax :

for(init ; condition ; increament);

{

statament;

}

Example:

A program to print no from 1 to 10

#include<stdio.h>

  void main() ;

   int i;

   for(i=1 ;i<11; i++)

{

     printf("%d",i);

}

 }

output:

12345678910

While Loop in c

A while loop  executes the statement till the condition is true.

Syntax :

while(condition);

{

statement;

}

Example:

A program to print no from 1 to 10

#include<stdio.h>

  void main() {

   int i;

  while( i<11 )

{

     printf("%d",i);

    i++; 

}

 }

output:

12345678910

Do While Loop in c

ans: If we want to execute a part of program several time then we use do while loop ,in do while loop statement or code executed at least one time

Syntax :

do

{

statement;

}while(condition);

Example:

A program to print no from 1 to 10

#include<stdio.h>

  void main() {

   int i;

 do

{

     printf("%d",i);

    i++; 

}

while(i<10);

 }

output:

12345678910

Break statement in c

ans:Break statement is used to break the loop.

Example:

A program on break statement

#include<stdio.h>

  void main() {

   int i;

 for(i=0;i<0;i++)

{

   if(i==5)

   {

    break;

   } 

    printf("no is %d",i); 

}

 }

output:

1234

Continue statement in c

ans:Continue statement is used to continue the statement.

Example:

A program Continue Statement

#include<stdio.h>

  void main() {

   int i;

 for(i=0;i<10;i++)

{

   if(i==5)

   {

    continue;

   } 

    printf("no is %d",i); 

}

 }

output:

123456789
