Write a program that prints the sum of digits of a number.
Write a program that prints the sum of digits of a number.
#include <stdio.h>
int main()
{
int n, s=0, r;
printf("\n Enter the Number: ");
scanf("%d", &n);
while(n>0)
{
r=n%10;
s=s+r;
n=n/10;
}
printf("\nSum of digits %d", s);
getch();
return 0;
}
<b>Output 1:</b>
Enter the Number: 123
Sum of digits 6
<b>Output 2</b>
Enter the Number: 1111
Sum of digits 4
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
