Syntax of for loop. Loops are used to repeat a block of code. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming -- many programs or websites that produce extremely complex output (such as a message board) are really only executing a single task many times.

Learning to write a compiler. Hi Stack Overflow, now don't get me wrong, I don't intend to write a compiler for C++(though I intend to write it in C++) or Java or some other high level complex programming language. A function declaration tells the compiler about a function's name, return type, and parameters.

A function definition provides the actual body of the function. The C standard library provides numerous built-in functions that your program can call. C Tutorial – Compilers (GNU and Visual Studio) A compiler is a program that translates one language (high level) into another language (e.g., assembly language or machine specific language).

C++ while and do...while Loop

A compiler translates source code (plain text) into object code (normally in a form suitable for processing by other programs (like a linker)).

For learning about how building a compiler is different in C++ than in, say, C or Pascal, try out the Boost Spirit parser framework. This assumes familiarity with C++. For learning about creating a compiler I suggest using a simpler language than C++, then perhaps advancing to C++.
