#include <iostream>

#include <ctime>

using namespace std;

int main()

{

    int num1;

    srand(time(NULL));

    num1=rand()%6+1;

    cout << num1;

In num1=rand()%6+1; 

1. rand() will generate a random number.
2. %6 is the range upto which you want to generate random numbers.
3. +1 will let you start number from 1 not from 0.
