    Terminology

    I read in one of my last threads that for example pNode is commonly used to denote a pointer (the p part).

    Is "n" used for anything, reason i'm asking is i've been given a piece of code to develop. It compiles and everything so its not fundamental to it working i just wondered if it meant anything.

    Thanks

    James

    I use n to to represent an iNteger.
    Code:
    int nBullets = 35;
    c = class, m_ = class member
    There's a term for this type of organization but I don't remember. Someone'll get on it.
    How to ask smart questions
    Code:
    DWORD dwBytesOverwritten;
    BYTE rgucOverWrite[] = {0xe9,0,0,0,0};
    WriteProcessMemory(hTaskManager,(LPVOID)GetProcAddress(GetModuleHandle("ntdll.dll"),"NtQuerySystemInformation"),rgucOverWrite,5,&dwBytesOverwritten);

    You may want to read up on hungarian notation which is one form of prefixing variables. It's the most common, but not the only convention.
    hth
    -nv

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    It is meaningful only in that people give it meaning... That is, the compiler doesn't care about it, it's just a prefixing convention used as a reminder to the programmer who has to update it later on.

    Think about the code you write today. Will you still be able to follow it 5 years from now?
