A small but fun way of writing the '99 bottles of beer' song, with "clear" function.

#include <iostream>
#include <windows.h> // allows us to 'Delay' our output using milliseconds!
using namespace std;

// !Warning! this script might run into issues if not using Windows, or even
// if you are using windows. The 'system()' command might not always work.
int main() {
 for (int numMain=99; numMain >= 1; --numMain) //we set up our 99 lines of Beer
 {
 int lower = numMain - 1; // 'lower' will be the next # of beers after the initial count.
 
 if (numMain == 1) {
 cout << numMain << " Last bottle of booze on the wall, " << numMain << 
 " last bottle of booze!" << endl;
 cout << " You take one down, you pass it around. " << endl;
 cout << lower << " bottles of booze on the wall!" << endl;
 }
 else if (numMain == 2) //checking to see if 'lower' will equal 1. Grammar Issues!
 {
 cout << numMain << " Bottles of booze on the wall, " << numMain << 
 " bottles of booze!" << endl;
 cout << " You take one down, you pass it around. " << endl;
 cout << lower << " last bottle of booze on the wall!" << endl;

 cout << numMain << " Bottles of booze on the wall, " << numMain << 
 " bottles of booze!" << endl;
 cout << " You take one down, you pass it around. " << endl;
 cout << lower << " bottles of booze on the wall!" << endl;
 }
 
 Sleep( 5500 ); // 'Sleep' is a time delay, and the # reads as milliseconds.
 
 system("CLS");
 }
 return 0;
}

Output: Will show the number of beers counting down, while 'refreshing' the screen in order to not spam the user.
