While Loop In C
A while loop is a control flow statement that repeatedly executes a block of
code as long as the specified condition is true.
Syntax:
while (condition)
{
// code to be executed repeatedly
}
{
// code to be executed repeatedly
}
// code to be executed repeatedly
}
Example of while loop in C to calculate the sum of numbers from 1 to 20:
Program:
#include <stdio.h>
int main()
{
int i = 1;
int sum = 0;
while (i <= 10)
{
sum += i;
i++;
}
printf("The sum of numbers from 1 to 20 is %d\n",sum);
return 0;
}
Output:
The sum of numbers from 1 to 20 is 210
