this question has answer here:
i got code:
#include <stdio.h> #include <conio.h> int rand(); int main() { int = 1; while (a<=15) { printf("%d\n", rand()); a++; } return 0; } funny thing print same list of numbers. thought print different numbers each time - , know there's must argument makes - surprised me program knows how print same values always.
so how possible, mean, i'm curious, seems sequence of number predefined executable.
you need initalise rand() srand() :
#include <stdio.h> #include <conio.h> #include <time.h> #include <stdlib.h> int main() { srand(time(null)); int = 1; while (a<=15) { printf("%d\n", rand()); a++; } return 0; } in short, need feed random seeds can work, want give him new seeds @ each run, use of time(null).
oh, , also, don't need declare int rand(); before main, instead add <stdlib.h> list of includes.
keep learning !
