I’ve been using an interpreted scripting language called Matlab to do my research work for some time now. I often type short commands straight into a command window to test the output before adding those commands to the main script. This really accelerates my development time. Now that I’m learning c++, I have become frustrated with having to recompile each time I want to test a small change to a calculation, or check my syntax. This is where Ch comes in. It is a freeware (for the standard edition) c++ interpreter which supports many functions and allows rapid checking of code fragments. The following screenshot is just me having a little play, while Ch seems to allow you to do so much more. I recommend you download and have a play!
