Error trying to use rand from std library cstdlib with g++
- by Matt
I was trying to use the random function in Ubuntu compiling with g++ on a larger program and for some reason rand just gave weird compile errors. For testing purposes I made the simplest program I could and it still gives errors.
Program:
#include <iostream>
using std::cout;
using std::endl;
#include <cstdlib>
int main()
{
cout << "Random number " << rand();
return 0;
}
Error when compiling with the terminal
