How Do I Find Static Memory Addresses?

// My first game hack. This is for "Sniper: Ghost Warrior"

#include "stdafx.h"
#include <iostream>
#include <Windows.h>

using namespace std;

int main ()
{
	HWND hWnd = FindWindow(0, L"Sniper: Ghost Warrior"); // Finds the window titled "Sniper: Ghost Warrior".

	if (hWnd == 0) // If it can't find the window, then:
	{
		cout << "Can't find window, dopey noonga!" << endl;
	}
	else
	{
		DWORD pr0c3zz;
		GetWindowThreadProcessId(hWnd, &pr0c3zz); // Locates the process through the window.
		HANDLE trollpr0c3zz = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pr0c3zz); // Gives access to process.
		if (!trollpr0c3zz) // If it can't access the process, then:
		{
			cout << "I can nawtz open pr0c3zz :(." << endl;
		}
		else
		{
			int ammoAmount = 10; // Amount of bullets in current round.
			int  roundsAmount = 60; // Amount of rounds left.
			int ammoAddr = 0x29500340; // Ammunition memory address.
			int roundsAddr = 0x296E629C; // Rounds memory address.

				cout << "Unlimited ammo - F1" << endl;

				bool AmmoHax = false;

			while(1) // Loops so the memory keeps rewriting itself if it's changed.
				{
                if (GetAsyncKeyState(VK_F1)) // If the "F1" hotkey is pressed then it will write the new data to the memory address.
						AmmoHax = !AmmoHax;

						if (AmmoHax)
						WriteProcessMemory(trollpr0c3zz, (LPVOID)ammoAddr, &ammoAmount, sizeof(ammoAmount), NULL); // Modifies the ammunition's memory value to 10.
						WriteProcessMemory(trollpr0c3zz, (LPVOID)roundsAddr, &roundsAmount, sizeof(roundsAmount), NULL); // Modifies the rounds' memory value to 60.

			} // End of loop.
				
		}
		CloseHandle(trollpr0c3zz); // Removes access to the process when it is not needed.
		}
	system("pause");
	return 0;
