What is the difference between %p and %x in C/C++?

Here we will see the difference between %p and %x in C or C. %p is used to print pointer values, %x is used to print hexadecimal values. Although pointers can also be displayed using %u or %x. If we want to print some value using %p and %x then we won't feel any major difference. The only difference that can be noticed is that %p will print some leading zeros, but %x will not.

Example

#include<stdio.h>
main() {
   int x = 59;
   printf("Value using %%p: %p\n", x);
   printf("Value using %%x: %x\n", x);
}

Output

Value using %p: 000000000000003B
Value using %x: 3b
