Good to write C++ - In this type of code? [closed]

Is good to write in C++ this type of code?

• Are any better way write it to understand it?

• Me write these codes with CodeBlocks and Notepad C++.

• Need to much time to search for all these functions.

Is this best way? No better way to write it?
