How do I find and edit Hello.cpp?

Question

I'm on a Mac, and working through the Hello World contract.

I managed to create the Hello.cpp file using the touch command in Terminal... but how do I find this file, and/or how do I edit it?

Answer 1

Open terminal and go to your home directory because it is the root directory of your all work directories . Go through this sequence

1.open terminal
2.# cd 
3.#locate hello.cpp

and you will find your file . now open your file like this using vim like this

vim hello.cpp

press i (to edit your file ) after editing press Esc than Ctrl+Shift+: and press wq (to save your file ) this will work if you have vim install to your system .

Answer 2

It is recommended to use eosiocpp for the purpose of initiating your contract.

Just run:

eosiocpp -n hello

Then:

cd hello && ls

And you will see two files hello.cpp and hello.hpp.

This is the good way to start writing your contract from scratch.
