Random Numbers

[Josus]

hello. Do you have an funcion that gives back "randomized" numbers. for example: ranomize(6) should return 0, 1, 2, 3, 4 or 5. know what I mean? I hope you can help me. I need this funktion for a simulation. The objects should decide by themselves in which direction they will go. :o) life is fun! Johannes //still a newbie

use the rand function to return a pseudorandom integer in the range 0 to RAND_MAX. Use the srand function to seed the pseudorandom-number generator before calling rand.

This works for me : srand( (unsigned)time( NULL ) ); // Initialise rand with the current time to get // a truly random seed int ivariable = rand() % 5 // result between 0 and 5

thanks Daffy d. wrote: int ivariable = rand() % 5 // result between 0 and that is exactly what I needed. I didn't know how to chance the RAND_MAX value! You helped me a lot! :o) life is fun! Johannes //still a newbie
