Is there a function to generate a random int number in C? Or will I have to use a third party library?
Note: Don’t use
rand()for security. If you need a cryptographically secure number, see this answer instead.
#include <time.h> #include <stdlib.h> srand(time(NULL)); // Initialization, should only be called once. int r = rand(); // Returns a pseudo-random integer between 0 and RAND_MAX.
On Linux, you might prefer to use random and srandom.
