random number generator: Keep track of certain numbers

[samintheoc]

Hello,
I am writing a program that generates random numbers with in the range [0,2].
I want to keep track of how many zeros are generated. I thought I had it with my if statement but it does not increment correctly. counter2 will increment sometimes when rand()%2 == 0 and other times not. Then it will also increment when rand()%2 == 1 or 2. Please help. Thanks

if (rand() % 2 == 0)
		{
			counter2++;
		}

  #include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>
using namespace std;

int main()
{

	srand(time(0));
	
	int counter2 = 0;

	for (int counter = 1; counter <= 120; counter++)
	{
                int x;
		cout << setw(4) << (x=rand() % 3) << "/";

		

		if (counter % 15== 0)
			cout << endl << endl;
		
		if (x == 0)
		{
			counter2++;
		}
                cout << counter2;

	
        }
	
	cout << "There were " << counter2 << " zeros counted" << endl;

	
        system("pause");

	return 0;
}

1) rand() % 2 can generate onlt 0 or 1
2) Line 17: you are generating random number and outputting it on the screen.
Line 24: you are generating another different random number and testing it for 0;

Any way someone could hint at how to reference the same pool of random numbers when calling rand() twice in same program? I am a struggling to figure it out. Thanks for the reply MiiNiPaa.

I'd save the rand() value to a variable in the loop that can be printed out and counted if 0.

Thank you. Seems so obvious after the fact but obviously not for me.
