if(varMax > 0){ srand(time(NULL)); // calc a random variable . srand time c null approach One problem with that approach is that if that random number comes from rand(), all you have achieved is to .

unique numbers using srand( ) and rand( ) functions in C++. Get C / C++ . Below is one way, among many, to approach this . > srand(time(NULL));//initialize random number generator

. srand(time(NULL . better approach would be this one: struct generate_rand { generate_rand() { srand(time(NULL . distribution in C/C++

int i, n=4, a, b, c,d; srand(time(NULL)); for (i=0; i < n; ++i) {a= rand() % 9 + 0; . I like that approach as well. I'd also like to offer a couple improvements if I may.

int main () { do { srand (time (NULL)); x = rand () % 10 + 4; c = rand () % 8 + 6; a = new char [x*c . I think you have the basic approach wrong for what you want to do. If I .

C @ DaniWeb - Hey I have to make the game War . I find this approach simplifies things a little. . srand (time (NULL)); //seed randomisation only once at start of game

function rand_chars ($c, $l, $u = FALSE) { if (! $u . one liner to give a bit of a fresh approach. The concept srand time c null approach is simple. The rand . $code = md5($rand . time()); echo "$code"; and if .
