The problem C++ IDE solves

Eliminates the need to set up a coding environment for competitive coders. Also, since it is web-based it can be accessed from anywhere.

Challenges I ran into

When I deployed this project I came to know that Heroku has a barebones Ubuntu running under the hood so we need to install gcc tools to make the C++ programs run, to solve this problem I set up a docker container and deployed the same on heroku. This container installs gcc tools.
