sum of digits in c++

int x, s = 0;
   cout << "Enter the number : ";
   cin >> x;
   while (x != 0) {
      s = s + x % 10;
      x = x / 10;
   }

C++ sum the digits of an integer

// 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;
}

digit sum c++

//1
	int n = 12345, sum = 0;
    while(n) {
        sum+=n%10;
        n/=10;
    }
    cout << sum; //15
//2
	int n = 12345, sum = 0;
    for (sum = 0; n > 0; sum += n % 10, n /= 10);
    cout << sum; //15
