Introduction
The program shows how to calculate sum of digits in a number. Here while loop is used. For example take the number as 345 then sum of digits is 12.
#include<stdio.h>
#include<conio.h>
void main()
{
int n,sum=0,remainder;
printf("/n Enter a number:");
scanf("%d",&n);
while(n!=0)
{
remainder=n%10;
sum=sum+remainder;
n=n/10;
}
printf("sum=%d",sum);
}
