how to make random numbers in c++ without repeating the
generated numbers? plsss help...ty

Hello edsel, thank you for the question.

If you want to create a random number in C++, there is a function called rand() that returns a random integer.

In order to seed the random number generator, you must call srand() prior to calling rand:

srand(unsigned int(time(0)));
int ranNum = rand();

rand() will return any random number, paying no attention to whether or not they repeat. If you want to display non-repeating random numbers, I'd suggest storing the return values of rand() in a vector, and then comparing the return of rand() against the vector values, simply calling it again if it repeats.

I hope this helps.

- Eddie
