Hi @preetgandhi1499, welcome to FCC. I don’t think there is a compiler for coding in C++ on FCC. I have only come across articles on cpp
The core ideas in the algorithms section work in any language. Personally, I think its good practice to work in multiple languages.
freeCodeCamp specifically teaches MERN stack web programming. As @JeremyLT said, the algorithm challenges could be used as practice in any language, but you would need to work on them in your own environment and write your own tests.
