To print the input value of a pointer, you need to use the printf function with a format specifier of "%p" instead of "%d" because pointers are memory addresses represented as hexadecimal values. The code would look something like this:
#include <stdio.h>
int main() {
int *ptr; // declare a pointer variable
int num = 5; // declare an integer variable
ptr = # // assign the address of num to ptr
printf("The input value of ptr is: %p\n", (void*)ptr); // use %p format specifier to print the address of num
return 0;
}
The output would be:
The input value of ptr is: 0x7ffee038d6dc
Note that the actual address value may vary depending on your system. Also, we cast the pointer to void*
to avoid a warning, as it is not guaranteed that int*
and void*
are of the same size.
