If I cast a pointer from int32_t to int8_t, why does the pointer’s value not change? I expected the resulting value to change from a 32-bit address to an 8-bit address.

When experimenting with the code below, it does not change. Why?

#include <stdio.h>
#include <stdint.h>

int main()
{
    int32_t * first = (int32_t *) 0xFFFFFFFF;
    int8_t * second = (int8_t *) first;

    printf("Gives: %p n", first);
    printf("Gives: %p n", second);

    return 0;
}
