C Program to Add digits of the number using single statement

Add Digits of the Number Using Single Statement :

#include<stdio.h>
int main() {
   int number = 12354;
   int sum = 0;
   for (; number > 0; sum += number % 10, number /= 10);
   printf("\nSum of the Digits : %d", sum);
}

#include<stdio.h>

int main() {

int number = 12354;

int sum = 0;

for (; number > 0; sum += number % 10, number /= 10);

printf("\nSum of the Digits : %d", sum);

}

Output :

15

How ?

for(initialization ; conditional ; increment)
{
  //body
}

for(initialization ; conditional ; increment)

{

//body

}

In ‘For Loop‘ Condition is first tested and then body is executed.
Carefully Look at Semicolon at the end of ‘For Loop’ , which tells us two Things -

For Loop is Bodyless.
Only Condition and Increment Statements will be executed.
