Control Instructions

Point out the error, if any in the while loop.

#include<stdio.h>
int main()
{
    int i=1;
    while()
    {
        printf("%d\n", i++);
        if(i>10)
           break;
    }
    return 0;
}

There should be a condition in the while loop

There should be at least a semicolon in the while

The while loop should be replaced with for loop.

No error

Answer: Option

Explanation:

The while() loop must have conditional expression or it shows "Expression syntax" error.

Example: while(i > 10){ ... }

Why does a while loop requires condition whereas for loop doesn't?

Ex: for(;;)
{
printf("%d\n", i++);
if(i>10)
break;
}

Please anyone help me.
