Thread: Displaying prime numbers using nested loops?

So I have a programming assignment in which I'm asked to display all of the prime numbers between 1 and 100 using nested loops. And I'm also asked to display the quantity of numbers that are primes between 1 and 100.

So here is the code I wrote that addresses the first part, but I didn't get to the second requirement yet.

Code:

	int x = 1;
	int loop2 = 2; 

	while (loop2<100){

		loop2++;
		x++;

		while (x < loop2){

			if ((loop2 % x != 0) && (loop2 < 100)){
				std::cout << loop2 << std::endl;
			}
			else if (loop2 % x == 0){

			}
			else{

			}
		}
		
	}

I haven't placed any statements in the else-if or else brackets because I don't need to do anything if they evaluate to be true.

So when I compile and run this, I see an endless repeating string of 3's in the output of the console. So I'm obviously doing something very wrong, and it has to do with my logic, but I can't figure out what exactly is wrong with my logic.

If someone could point me in the right direction with regards to what is wrong with my logic, I would really appreciate it!

Code:

        int x = 1;
	int loop2 = 2; 

	while (loop2<100){ // 2 < 100 is true, proceed

		loop2++; // loop2 = 3
		x++; // x = 2

		while (x < loop2){ // 2 < 3 is true, proceed

			if ((loop2 % x != 0) && (loop2 < 100)){ // (3 % 2 != 0) is true && (3 < 100) us true, proceed
				std::cout << loop2 << std::endl; // print 3
			}
			else if (loop2 % x == 0){

			}
			else{

			}
		} // end of loop body, return to top, (2 < 3) still true, rinse, repeat...
