    Reading a user specificed line from a file

    I am trying to write a function to read a specific line from a file and assign it to C++ String type.
    I have opened the file using fopen and I do not know the length of the individual line of the file. Is there a library function that reads the whole line (line number specified by the user) using a delimiter? (say '\0' terminated strings)

    Use the global getline function.

    The first parameter is the stream.

    The second parameter is the std::string object to store the line.

    And while you're at it, take a look at the C++ Forum since you're actually on the C board.

    Hope is the first step on the road to disappointment.

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
