There's other better random number generators but this one is the usual one for exercises:

std::random_device randomizer;
int random_nr=randomizer()%4;

[cmajor1]

which library do i need for this ?

#include<random>

[OverSurge88]

#include <iostream>
#include <string>
#include <ctime>

using namespace std;

int main()
{
int randNum;

srand(time(NULL));
randNum = rand() % 2 + 1;

// %( modulus) 2 + 1 tells the program that


system("PAUSE");
return 0 ;
}
