    Brian Bi Considerably more pleasant. You can write auto instead of std::map<std::string, std::vector<int>*>::iterator, or some other ugly type. You can use range-based for loops. You can use lambda functions instead of defining new functions or classes out-of-line just so you can use them in...

    What is the fastest time a person can create a minesweeper game using C?

    Garry Taylor For me, C wouldn’t be the issue, it’s that I’ve not created a graphical program in C in probably over 10 years. For a simple game like this, the issues of building things in C don’t really come into it, it’s more familiarity with a GUI library or toolkit which would be my...
