add header file

Question

anyone tell me how to add header file while code C++ in Code Playground?
thanks !!!

Answer 1

Im afraid in the Code Playground you can only use common header files such as <iostream>, <cmath>, etc... by binding them in through #include.
Using your own designed header files is not possible, the compiler is sadly limited in that way here, so you'll have to code everything in one file.

Oh. Thanks
