While Loop Problem.

[Idiotal]

#include "stdafx.h"


#include <iostream>
int main(){
	int a;
	int aUnits;
	int aTenths;
	int aHundredths;



	while (aUnits = 1, aUnits <= 9){

		while (aTenths = 10, aTenths <= 90){

			while (aHundredths = 100, aHundredths <= 900){


				aUnits++;
				aTenths++;
				aHundredths++;
				while (aUnits + aTenths + aHundredths < 1000){



					a = aHundredths + aTenths + aUnits;


					std::cout << " " << std::endl;
					std::cout << a;
				}


			}
		}
	}
}

When I put in the last while statement it just keeps on printing 114 forever, if I don't write that last while statement, it keeps on looping till infinity of numbers, can't figure out why.

Not completely sure, but shouldnt last while loop be something like this ?
while (a < 1000)

I tried that before this, same result.

You never change anything in the body of the inner while loop, so the test is always the same and the value of a is always the same, therefore an infinite loop.
