What is the difference between %x and %p format specifier ?

[radha gogia]

int *p ;
printf("%p" , p);

This code printed 7EFDE000

When I used the format specifier %x , then it printed 7efde000

so its just changing the upper case letters to lower case letters , so then whats the basic difference between these two while printing address values ?

The %x is used for unsigned hexadecimal integers.

The pointer is not a hexadecimal integer but the %p will display the address in the pointer in hexadecimal.
