Sometimes,it is required to jump out of a loop irrespective of the conditional test value. Break statement is used inside any loop to allow the control jump to the immediate statement following the loop.
Syntax:
break;
When nested loops are used, then break jumps the control from the loop where it has been used. Break statement can be used inside any loop i.e. while,do-while, for loop and also in switch statement.
Example
program to calculate the first smallest divisior of a number
#include<stdio.h>
void main()
{
int div,num,i;
printf(”enter any no.\n”);
scanf(”%d”,&num);
for(i=2;i<=num;i++)
{
if(num%i==0)
{
printf(”smallest divisior is %d”,i);
break;
}
}
}
Output
enter any no.
9
smallest divisior is 3
In above program,we divide the input number with the integer starting from 2 onwards, and print the smallest divisor as soon as remainder comes out to be zero. Since we are interested in first smallest divisor and not all divisor of a given number so jump out of for loop using break statement without further going for next iteration of for loop.
