Can I edit the RAM with pointers on C++?

Question

Using pointers, can I check all the RAM searching one value? How can I do it? Something like what Cheat Engine do it

Answer 1

Sorry but in normal circumstance your program cannot access to all memory

Answer 2

i think cheat engine uses the win32 api function ReadProcessMemory or similar calls. there is also a lot of undocumented stuff in the win33 api that it might use
see this link https://msdn.microsoft.com/en-us/library/ms680553%28VS.85%29.aspx
and the links at the bottom of this page
if the program uses cheat protection or similar methods to protect itself it might be necessary to hook functions in the kernel32.dll or similar files
