Can't initialize with this fraction

Question

I can't get variable "dis" to initialize with an expression that includes a fraction. The output for the "dis" variable is "0" other than when I replace the expression with a constant.

Any insight would be greatly appreciated.

Code:

#include <iostream>
using namespace std;

double getDis(int var)
{

double dis;
dis = (50/100)*var;

return dis;
}

int main() {
int ages[5];

for (int i = 0; i < 5; ++i) {
cin >> ages[i];
}
//your code goes here

double min {ages[0]};
for (int i = 1; i < 5; i++)
{
if (ages[i] < min)
min = ages[i];
}
//cout << "min = " << min << endl;
double dis{getDis(min)};
//dis = (50/100)*min;

double cost {50-dis};
cout << cost;

return 0;
}

Answer 1

(50/100) returns 0 since neither operands are double. Try (50.0/100), and yeah, you should be returning double from the function too, not int.

Answer 2

Int type will remove all the values after decimal point. Maybe use float or double.

Answer 3

Arran change the type of function as well otherwise it will return an int .

Answer 4

Thank you both for taking the time to solve my issue

Answer 5

Thank you for the advice. It returns 0 whichever type I use. I just noticed my function had int and replaced with double, and it again returned 0.

Answer 6

Hatsy Rei, that was exactly the issue, thank you!
