I used this to teach @lordofsraam how pointers work and how you can use them to store more than one value in memory (which is what every C string does but this is slightly different)

PointerHacking.cpp

#include <new>
#include <cstring>
#include <stdlib.h>
#include <iostream>
#include <cstdio>
#include <malloc.h>

int main(int argc, char **argv)
{
	size_t *ptr = (size_t*) malloc(11);//malloc(3 + sizeof(size_t));
	printf("Malloc()'d pointer at: %p\n", ptr);

	size_t blah = 11;
	*ptr = blah;

	printf("Ptr: %p\n", ptr);
	printf("Val: %ld\n", *ptr);

	printf("Changing memory space\n");
	ptr++;

	char *str = (char*)ptr;
	
	*str = 'H';
	str++;

	*str = 'i';
	str++;

	*str = 0;

	//strcpy((char*)ptr, "Hi");

	printf("Val: %s\n", (char*)ptr);
	printf("Ptr: %p\n", ptr);

	ptr--;
	printf("Reverting to original memory context\n");
	printf("Ptr: %p\n", ptr);
	printf("Val: %ld\n", *ptr);

	printf("Free()'d pointer at: %p\n", ptr);
	free(ptr);

	return 0;
}
