How to generate a random int in C?

Question

Is there a function to generate a random int number in C? Or will I have to use a third party library?

Answer 1

This is hopefully a bit more random than just using srand(time(NULL)).

#include 
#include 
#include 

int main(int argc, char **argv)
{
    srand((unsigned int)**main + (unsigned int)&argc + (unsigned int)time(NULL));
    srand(rand());

    for (int i = 0; i < 10; i++)
        printf("%d\n", rand());
}
