#include<stdio.h>
#include<conio.h>
main()
{
int n,i,sum=0,r;
printf("enter the value");
scanf("%d",&n);
while(n>0)
{
r=n%10;
sum=sum+r;
n=n/10;
}
printf("sum = %d",sum);
}
output:
3456
how it works as follows:
3456%10 means it gives reminder as 6
6 will be added to the sum
3456/10 means it gives quotient as 345
then again loop is executing until the n value is 0
finally the result as 6+5+4+3=18
