easy source code for modifying ammo, money, amount of items and such

[gogogokitty]

this is not mine, i just filled it in and added examples for people that are newer to c++ than me if thats even possible. credits go to PerfectsDaily

#include "stdafx.h"
#include <iostream>
#include <Windows.h>
#pragma comment(lib, "user32.lib")

using namespace std;


int _tmain(int argc, _TCHAR* argv[])
{

	cout << "gogogokitty199's contagion ammo modifier\n"; //first display message
	cout << " \n";

	HWND hWnd = FindWindow(0, L"Contagion"); //name of the game window, example (Contagion, Dayz, ect)
	if (hWnd == 0){
		cout << "could not find Contagion.exe . Please verify that your game is running!\n";
	}
	else {
		cout << "Found Contagion \n";

		DWORD proc_id;
		GetWindowThreadProcessId(hWnd, &proc_id);

		HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proc_id);
		if (!hProc) {
			cout << "error could not find the process \n";
		}
		else {
			cout << "Opened Contagion. \n";
			
			DWORD Pointer = 0x018EF124;		 //change the static pointer to one of a game that you want, just an example and this isnt correct
			DWORD Pointed;
			WORD Offset = 0x0;		//offset for the pointer
			int CurrentAmmo = 0;	  //read ammo, money, items ect
			int newValue;

			ReadProcessMemory(hProc, (LPCVOID)(Pointer), &Pointed, 4, NULL);
			ReadProcessMemory(hProc, (LPCVOID)(Pointer + Offset), &CurrentAmmo, 4, NULL);

			cout << "Enter your desired amount of ammo, max is 250: ";  //this is just for contagion, ammo in mag limit is 250 max
			cin >> newValue;

			int Success = WriteProcessMemory(hProc, (LPVOID)(Pointed + Offset), &newValue, (DWORD) sizeof(newValue), NULL);

			if (Success > 0){

				ReadProcessMemory(hProc, (LPCVOID)(Pointer), &Pointed, 4, NULL);
				ReadProcessMemory(hProc, (LPCVOID)(Pointer + Offset), &CurrentAmmo, 4, NULL);
				cout << "your ammo has been loaded into your mag \n";   //write success
				cin.get();
				cout << "Press Enter to close \n";
			}
			else{
				cout << "Error could not write to process memory";        //write failed
				cout << "Press Enter to close \n";
				cin.get();
				
			}
		}
	}
		cin.get();
		return 0;
}

i used contagion as a base example because its easy and simple.
