    Newbish Question On String Extract

    How would I extract a string from an input file? Just need to know what function to use. For example in this line:
    Need to extract "klm" into an array.

    Use the memberfunction getline in cin. This has been covered several times. Make a Search here

    P.S if you are using MSVC there is a bug in the header files for getline. Solution: a search again

    One solution is std::getline().

    string sInput;
    std::getline(cin, sInput);
    size_t nFind = 0;

    if ((sInput.find("klm")) != sInput.npos)
    string sKey = sInput.substr(nFind, 3);
