Getting Set Up - C++ Compilers The very first thing you need to do‚ before starting out in C++‚ is to make sure that you have a compiler. What is a compiler‚ you ask? A compiler turns the program that you write into an executable that your computer can actually understand and run. If you’re taking a course‚ you probably have one provided through your school. If you’re starting out on your own‚ your best bet is to use Code::Blocks with MinGW. If you’re on Linux‚ you can use g++‚ and if you’re on
