Read whole ASCII file into C++ std::string [duplicate]

Answer 1

If you happen to use glibmm you can try Glib::file_get_contents.

#include 
#include 

int main() {
    auto filename = "my-file.txt";
    try {
        std::string contents = Glib::file_get_contents(filename);
        std::cout << "File data:\n" << contents << std::endl;
    catch (const Glib::FileError& e) {
        std::cout << "Oops, an error occurred:\n" << e.what() << std::endl;
    }

    return 0;
}
