I was working on something else, but everything came out as zero, so I made this minimalistic example, and the output is still 0.
#include <iostream>
int main(int argc, char** argv)
{
double f=3/5;
std::cout << f;
return 0;
}
What am I missing?
You are missing the fact that 3 and 5 are integers, so you are getting integer division. To make the compiler perform floating point division, make one of them a real number:
double f = 3.0 / 5;
