Code compiles, but no console output

Question

My C++ code compiles and runs, but no output is printed to the console. I think it has something to do with the string variables, but im not sure. Im a total noob, any help would be appreciated. I am using codeblocks with GNU GCC Compiler.

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string botlong, botshort, secondline;
    botlong = "bottles of beer on the wall,";
    botshort = "bottles of beer";
    secondline = "Take one down and pass it around,";
    for(int bottles = 99; bottles<=0; bottles--)
    {
        cout<<bottles <<botlong <<bottles <<botshort;
        for(int lostB = 98; lostB<=0; lostB--)
        {
            cout<<secondline<<lostB<<botlong;
        }
    }
    return 0;
};

Hmm. Tried adding a new line to your strings? like doing ' << endl '. Depending on your environment, strings without newline might have strange effects ... — GhostCat

@alifirat is right, you should flush the stream (or any stream for that matter) before the program ends. — Timo

It must be >= instead of <=, otherwise your loops are not entered:

for(int bottles = 99; bottles >= 0; --bottles)
{
  cout << bottles << botlong << bottles << botshort;
  for(int lostB = 98; lostB >= 0; --lostB)
  {
    cout << secondline << lostB << botlong;
  }
}

That was it. I appreciate the help. I guess with the way I had it, the expression (bottles <= 0) was never true, so it never entered the loop. Thanks a bunch for helping me understand this!

I think your condition in for loop doesn't hold on start. You have a typo, correct bottles<=0 to bottles>=0 and same with next for loop.
