Why it is giving the 0 answer?

Question

#include <iostream>
using namespace std;
int main()
{
double basic = 1000;
double DA = (10/100) * basic;
double HRA = (30/100) * basic;
cout<<"DA = "<<DA<<endl; // why the answer is 0 ?
cout<<"HRA = "<<HRA<<endl; // why the answer is 0 ?
return 0;
}

Please Help me....I do not understand why the DA and HRA is giving 0 answer?

The question should be updated to include desired behavior, a specific problem or error — JHBonarius, Dec 20 '20 at 17:44
10/100 is 0 -- this is integer math. 10.0/100.0 would be 0.1. — TCvD, Dec 20 '20 at 17:46

10/100 = 0 as 10 and 100 are both int and their result will aslo be int.

Try 10/100.0

30/100.0
