I have an Acer Chromebook and wondered if anyone has used any of the C++ compilers in the Google app store for the Chromebook or can recommend a Compiler that is known to be good one for the Chromebook...many thanks, John

Hopefully this helps:

There is also Compilr.com, an online IDE and Compiler which you need to pay for.
