Example 1: C++ sum the digits of an integer
int getSum(long long n){
int sum = 0;
int m = n;
while(n>0) {
m=n%10;
sum=sum+m;
n=n/10;
}
return sum;
}
Example 2: add two numbers in c++
#include <iostream>
using namespace std;
int addition(int a,int b);
int main()
{
int a,b;
int add;
cout<<"Enter first number: ";
cin>>a;
cout<<"Enter second number: ";
cin>>b;
add=addition(a,b);
cout<<"Addition is: "<<add<<endl;
return 0;
}
int addition(int a,int b)
{
return (a+b);
}
