If I don't specify srand(), what seed does rand() use?

Question

Here is the code:

#include 
#include 
#include 

int main(void)
{
    int r;
    int i;
    for (i = 0; i < 1         


        

Answer 1

The srand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned by rand(). These sequences are repeatable by calling srand() with the same seed value.

If no seed value is provided, the rand() function is automatically seeded with a value of 1.
