Question

The function below runs, but always returns the same numbers each time I run the program. Is there a way to generate random numbers that are different each time I run the program?

int getrand(int min,int max){
 int rnum = rand()%(max-min)+min;
 return rnum;  
} 

Answer 1

a simple solution to randomize once would be:

int getrand(int min, int max) {
  static bool init = false;

  if (!init) {
    srand(time(NULL));
    init = true;
  }

  return rand()%(max-min)+min; 
}
