i don't know if this is what your looking for but

#include<iostream>
#include<ctime>
#include<cstdlib>

using namespace std;

int main()
{
srand(time(0));
int num = ((rand() % 3) + 1);
cout<<num;
int x;
cin>>x;

return 0;
}

Language? Platform?

The typical C solution is to obtain the modulus of the rand() function and the upper bound. This has problems with certain implementations of the C runtime because the lower bits have less randomness than the overall value.

In C.

number=rand()%2; //0-1
number=rand()%3; //0-2
number=rand()%4; //0-3
number=(rand()%2)+1; //1-2
number=(rand()%2)+3; //3-4
