Learning C++

C++ is a high-level and and an object orientated programming language (it can have parts known as classes or object). Why C++? It is an extension to C (adds new features)

Compiling

• The compiler checks the code and is needed to translate your code for your hardware or computer (object file)
  • https://nl.wikipedia.org/wiki/Compiler
• it produces a stand-alone executable program
  • process diagram: diagram
• compiling is used for C, C++ and Pascal
• compilers exist for multiple CPUs
  • diagram
• Compile a .c file with g++ filename.c -o executablefilename
  Also possible:
• interpreting:
  • executes the instructions directly
  • every time you run the program you need the interpreter
  • for scripting languages (Perl, JavaScript)
• Java ues a mix of the two

Linking

• combines the object files to single executable
• links library files

Libraries

Libraries are precompiled 'packages' for reuse in other programs.

• use #include <library> to include a library in the program

Different libraries

• standard:
  • iostream: for input and output capabilities

TODO:

• visual studio compiler (Desktop development with C++)
• cin.ignore
• cin<< (output) and cin>> (intput)
