program to find sum of digits of a number

program to find sum of digits of a number

Sum of digits means add all the digits of any number, for example we take any number like 358. Its sum of all digit is 3+5+8=16. Using given code we can easily write c++ program.

#include<iostream.h>
#include<conio.h>
void main()
{
int a,no,sum=0;
clrscr();
cout<<"Enter any num : ";
cin>>no;
while(no>0)
{
a=no%10;
no=no/10;
sum=sum+a;
}
cout<<"\nSum of digits: "<<sum;
getch();
}
