Need help with this. Its compiling but its printing out nothing. It must be something with the for loop. ANy ideas? This is due in an hour and im just about to throw in the towel... figured id come here first.

Thanks:

CODE
#include <iostream>
using namespace std;

bool isleapyear(int a) {
  return ((a % 4 == 0 && a % 100 != 0) || a % 400 == 0);
}  

int main () {
 
  int x, y;
  cout << "Please enter starting and ending years of a range of years: ";
  cin >> x >> y;
  cout << endl;

  if(x > y){
     cout << "Enter a starting date earlier than the ending date: ";
     cin >> x >> y;
  }
 
  for (int i = 1; i >= x && i <= y; i++){
     if (isleapyear(i)) {
        cout << i << " " << endl;
     }
  }

It's your loop condition...starting at one does not allow loop execution in this case, try changing the loop to:
CODE

 for (int i = x; i <=y; i++){
    if (isleapyear(i)) {
       cout << i << " " << endl;
    }
 }

I tested it with 1900 and 2000...worked for me.
