terminal setup

For me I am using fish shell in termux for now so here is the steps

• make a function inside ~/.config/fish/functions
• for me I named it cr.fish .
• after saving the code restart the fish shell or open a new terminal .
• than you can use the function

how you will use it

> cr basic_data_types.cpp

Compiling basic_data_types.cpp with g++...
