Have been thinking about attempting to learn SDL (Simple DirectMedia Layer) for a wee while so what better way to spend a day off. It didn’t start well however
Here’s a typical example “Hello World” program in Visual Studio.
Look what happens when I attempt to include the SDL header. My main function becomes a member function and therefore won’t build.
Undefining main fixes the issue thanks to rodrigo at good ol’StackOverflow.
About a year ago, I started writing a little database program for the console (just a simple little thing to modify, add, and subtract items from a SQL-Lite database) and I wanted it to be colourful. However, the codes aren’t that much fun to type in so I came up with a crude implementation of something that could create a header file for me to handle exactly that.
It wasn’t pretty, and a year on with a little extra C++ knowledge under my belt I came up with this to replace it.
This creates a header file and also a nice output listing to print out.
Edit: I’ve since given it a third revision that outputs the codes to a console window rather than to an output file, which kind of made a bit more sense. I can copy/paste it to a future post if someone wants it.
// Program to output a definition header file for Windows Console colours

/* Output Header file */
ofstream outFile;
outFile.open("ConsoleColours.h");
outFile << "#ifndef ConsoleColoursH" << endl;
outFile << "#define ConsoleColoursH" << endl;
outFile << " " << endl;
/* Output Nice Listing */
ofstream niceList;
niceList.open("ConsoleColours-Nice.txt");
string listColours[16] = { "DARK_BLUE", "GREEN", "TEAL", "RED",
