why rand function keep returning 41 or same value as output?

Question

we can use this code to generate random number but i don't know how it works?

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
int a;
srand ( time(NULL) );
a = rand();
printf("%d",a);
return 0;
}

Answer 1

If you don't randomize the seed using srand, your rand function will always return the same number. That's why you have to do this
