Can somebody tell me whats wrong in my code to find the area of triangle. It always show result as 0.

Question

#include <iostream>
using namespace std;
int main ()
{ int a , b;
cout << "ENTER THE BASE OF TRIANGLE \n";
cin >> a;
cout << "ENTER THE HIGHT OF TRIANGLE \n";
cin >> b;
int sum = (1/2)*a * b;
cout << sum; return 0; }

Answer 1

change (1/2) to (1.0/2) or (1/2.0)
because (1/2) is integer division so it will return 0.

Answer 2

Use floats or doubles instead of int

Answer 3

float a, b, area;
area=(1/2) *a*b
