    Thumbs up Random numbers (about the tutorial)

    The tutorial displays the following code on how to generate random numbers...
    Code:
    #include <stdlib.h> //for rand
    #include <stdio.h> //for printf
    #include <time.h>   //for time
    
    int main(void)
    {
        srand(time(NULL));
        printf("A random number from 0 to 99: %d", rand() % 100);
        return 0;
    }
    My question is: how do i change this snippet so that it uses the cout << thing instead of the printf thing. If this is not possible, please explain why and tell me if I should continue to use the cout << thing or just go with the printf thing.

    Thanks

    Code:
    #include<cstdlib>
    #include<iostream>
    #include<ctime>
    using namespace std;
    int main()
    {
    srand(time(NULL)); 
    cout<<"A random number from 0 to 99 :- "<<(rand()%100);
    return 0;
    }
