c++ random int function 3 answers

i'm trying create 2 random numbers (between 0-4 , 0-10) in each time cycle occurs, give same number. if run programme multiple times, gives different numbers, while cycle generates same 2 numbers. thanks.

int random(int range){ int num; srand(time(null)); num = rand() % range; homecoming num; } int main(){ int cnt = 0; int i; int j; while (cnt <= 20) { = random(5); j = random(10); printf("%d\n",i); printf("%d\n",j); printf("\n"); cnt += 1; } homecoming 0; }

you need seed random number generator once.

so run line outside of random function:

srand(time(null));

.. in main function instead:

int random(int range){ int num; num = rand() % range; homecoming num; } int main(){ int cnt = 0; int i; int j; // seed random number generator srand(time(null)); while (cnt <= 20){ = random(5); j = random(10); printf("%d\n",i); printf("%d\n",j); printf("\n"); cnt += 1; } homecoming 0; }

c loops random
