Write a C Program to Add Digits of a number in C.
#include<stdio.h>
int main()
{
int a,sum=0,temp; //’a’ for user defined number, ‘sum’ for store the result, ‘temp’ is temporary variable
printf(“Enter a number :”);
scanf(“%d”,&a);
for(temp=a;temp>0;temp=temp/10)//removing last digit from the temp variable for the next iteration.
{
sum=sum+(temp%10);//adding last digit of the temp to the sum.
}
printf(“Addtion digits of given number is : %d”,sum);
return 0;
}
Output :
i) Enter a number : 25461
Addition digits of given number is : 18
