Answer 1

Hey Surya Raj
1. What is %x , I don't understand?
2.is your question that you are getting some value for 1st and 2nd printf fn ,they are the memory address of that variable.

I think this code help you 👇
#include <stdio.h>
int main() {
int j = 63;
int *p=NULL;
p = &j;
printf("The address of j is %ld\n", &j);
printf("p contains address %ld\n", p);
printf("The value of j is %d\n", j);
printf("p is pointing to the value %d\n", *p);
return 0;
}

Answer 2

Surya Raj , The correct format specifier for printing address is %p.
Replace %x with %p.

Answer 3

It is printing one type of garbage value because the value changes when you re-run it
