    I really could use some help

    Hi.
    I wanted that I could typ in the name of the file I wanted to read/write but he gives me an error:

    Code:
    string LoadFileName;
    
    ifstream Checking ( LoadFileName );// Line 35
    Is it that he can't read/write a string as file name?

    Here is the error message:
    Code:
    35 C:\Documents and Settings\Admin\Bureaublad\Time\Time.cpp no matching function for call to `std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(std::string&)'
    
    note C:\Dev-Cpp\include\c++\3.4.2\iosfwd:90 candidates are: std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)

    The file stream classes take a const char* for the file name, so you just need to call the .c_str() function to pass one. It should be:

    ifstream Checking ( LoadFileName.c_str() );
