sum of digits c++ code example
Example 1: 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;
}
Example 2: 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;
}
Example 3: 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
