#include <stdio.h>
#include <stdlib.h>

int main() {
    char *ptr_two = (char *) malloc(sizeof(char) * 50);
    printf("%p\n", ptr_two);
    free(ptr_two);  // free memory here, since we are going to assign a string to it on next line.
    ptr_two = "A constant string in C";
    printf("%p\n", ptr_two);
    printf("%s\n", ptr_two);
    return 0;
