I wrote some code to A) Play with some c++ cause I took the class a while ago and want to start programming again. and B) I read something on xkcd.com and wanted to check it out....
for some reason, I can't get this to compile at all! I don't have any idea why.
Here is my code just checking syntax and stuff. clearly I am missing something.
#include <iostream>
using namespace std;
int main()
{
long int x,y,z;
cout << "enter x" << endl;
cin >> x;
y = x/2;
z = 3*x + 1;
cout << "x = " << x << endl << "y = " << y << endl << "z = " << z << endl;
return 0;
}
And here is the screen of text that I get when I try gcc collatz.cpp
