Question

/* i know if i just threw his into a script it probably wouldnt work but am i on the right track?*/

#include <iostream>
using namespace std;

int main(){
//global vars_________________________________________
int x;
int *xp
*xp = &x;
int lvl;
int *Plvl;
*Plvl = &lvl;
int EHealth;
int *PEHealth;
PEHealth = &EHealth;
int PHealth;
int *PPHealth;
*PPHealth = &PHealth;

Answer 1

-You need a semicolon after int *xp.

-Instead of doing

int x;
int *xp;
*xp = &x;

Do:

int *xp = new int;

The above allocates memory for an integer, and stores the address in the xp pointer. (Note I did not say the *xp pointer - this is because *xp dereferences the xp pointer, and rather than signifying the pointer itself, signifies the value it points to.)
-This is why

*xp = &x;

is incorrect - you are setting the value that xp points to the address of x
-This is correct:

xp = &x;

-When your pointers become unnecessary:
delete randompointer;

Remember when we said that "new" allocates memory? "delete" frees that memory up so that it can be used again. (deallocation)

I apologize for my long winded explanation - I like to be a little too thorough. 😀.

Answer 2

Aaand remember to delete every pointer you have created. E.g.:
delete xp;
Program cannot delete dynamic allocations, and if you won't delete pointer there's going to be memory leak.
