C++ COMPILE & EXECUTE

C++ COMPILE & EXECUTE

   C++ is a compiled language. That means that to get a C++ program to run, you must first translate it from the human-readable form to something a machine can "understand." That translation is done by a program called a compiler.

What did I do

 Code → Save → Compile → Execute

1. Code — writing the program
2. Save — saving the program
3. Compile — compiling via the terminal
4. Execute — executing via the terminal

Compile (编译) hello.cpp using the terminal.

g++ hello.cpp

Execute(执行): To execute the new machine code file, all you need to do is type ./ and the machine code file name in the terminal:

./a.out

The a stands for "assembler" and the out stands for "output". 

• -Single line comment can be done using //.
• -Multi-line comment can be done using /* */.

Note: Codes in the terminal can not be erased once summitted, so if you made a mistake, you'll have to reset the whole thing.
