Speedhack in c++

Hi there,
im also looking for a c++ speedhack tutorial.
Atm. i know how to find the adress with cheat engine but i have no idea how can i write this in c++.
Im a beginner in c++ and i only know the basics yet.

This is what i have:

Code:

---

Base Adress        Offset 0        Offset 1        offset 2        offset 3        offset 4        Points to:
"Gw2.exe"+011E5690    44              1c              5c              0              114        05FE7530

---

The normal speed is 11.484375 so maybe speed on will be 14.484375 or 16.484375
So i need to know how to bind the speed to SHIFT or any other keybind. If i press and hold the key speed xy is on if not its off. Sound simple but not for a beginner :)

I hope anyone can help me.

thank you
