Random number generation

[sophtwarez]

Hello all - how can I generate a random number *at run time* in C++? I'm thinking of something like Visual Basic's Rnd or, in Java, Math.random().
I've used rand() and it always generates the same number after compilation.

Thanks much,

Did you want something like this???

#include <stdlib.h>//you may need to include

srand((unsigned)time(NULL)); //Only needs to be used once
Variable = rand()%20;//'20' is the max number

Hope this help.
