[c + +] Basic Ideas and Style guide

Get your own compiler:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.9
You can then compile using the Command:
g++-4.9 -std=c++14 -wall-werror-o2-o HelloWorld helloworld.cpp

Style Rules:

Macros should never is required in C + +.
Variables should is defined close to theiruse.
Don ' t use malloc/realloc, use new (or Smart Pointers)
Minimise use of void*, pointer arithmetic, Union and C-style casts
Minimise the use of c-style arrays and strings, use Vector/array (from c++11) and string instead.

In short, forget the C language.

C + + Standard Library

For efficiency reasons, STL are not object-oriented:

• Makes little use of inheritance, and
• Makes no use of virtual functions

The standard Template library (STL) was a part of the C + + library, Some others is:

Category One:

• The C Standard library
• Language support: <exception>, <ctime>,...
• Strings: <string>, <cstring>,...
• Numerics: <cmath>, <complex>,...
• I/o: <iostream>, <fstream>, <cstdio>,...
• Exception classes
• Smart pointers
• Classes for internationalisation support

Category Two:

Containers: vector, list, stack, ...
algorithms: find, sort, copy, ...
iterators is the glue between the two!

The compilation Process:

1. Preprocessing-handles meta-information (e.g., #include)
2. Compiling-translates C + + into machine code objects
3. Linking-merges objects into a single application

The practice of language style is the best way to Learn. Understanding the Author's style of thinking, it means that language learning has reached a good standard.

The road is long ... There is no shortcut except Persistence. Good luck!
