How do I read long lines from a text file in C++?

Question

I am using the following code for reading lines from a text-file. What is the best method for handling the case where the line is greater than the limit SIZE_MAX_LINE?

Answer 1

Since you're using C++ and iostream already, why not use std::string's getline function?

std::string acLine;
while(xInFile){
    std::getline(xInFile, acLine);
    // etc.
}

And, use xInFile.good() to ensure eofbit and badbit and failbit are not set.
