rand question

[allenanaima1]

how can i make this function give me random number each time i run it? rather than just give me the same numbers everytime
thank you

#include "Dice.h"
#include <stdlib.h>


Dice::Dice()
{
    sides = 6;
}

int Dice::roll()
{
    return (rand() % sides + 1);
}


DiceLoad::DiceLoad() {
    sides = 6;
}

DiceLoad::DiceLoad(int numSides) {
    if (numSides > 0) {
        sides = numSides;
    } else {
        sides = 6;
    }
}

Dice::Dice(int numSides)
{
    if (numSides > 0) {
        sides = numSides;
    } else {
        sides = 6;
    }
}


int DiceLoad::roll() {
    int value = (rand() % sides + 1);
    int random = (rand() % 100 + 1);

    if ((value < 6) && (random >= 95)) {
        value = value + 1;
    }

    return value;
}

You need to call srand() in main or something. The key is to only call once per program run.
