How do you do random things with C++. If someone has written a dice roller or random number genorator, if they could post it here that would be great. And maybe explain it a bit. Thanks.

Include <cstdlib> and make use of the srand and rand functions. Some info on how to use them can be found here.

Almost anything is pseudo random, many links can be found on this forum and even more on google, like here.

N'Sync... I thought that group was dead. Justin is singing solo now isn't he?

Like this?

(Toggle Plain Text)

// Die Roller

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

using namespace std;

int main()
{
    srand(time(0));  // seeds the random number generator based on the current time
    
    int randomNumber = rand();  // generate random number
    
    int die = (randomNumber % 6) + 1; // get a number between 1 and 6
    cout << "You rolled a " << die << endl;
    
    return 0;
}

Pretty self explanatory, and a rather simplified version of a dice roller.
