Brief Notes C Language: Term and Program Structure

 This is just my note when I attended the lecture. I write this here so it will be long lasting.  :D

[ The Terms in C ]

There are several terms used in C:

Block is a set of expression written between '{' and '}' mark;

Definition tells the property(ies) of an object and allocate the object's memory as well;

Declaration tells the property(ies) of an object especially related to type;

Initialization gives the initial value to the object;

Global Declaration is the declaration which is valid in one unit translation (file);

Local Declaration is the declaration which is only valid in one block this declaration placed;

Object also known as a variable;

Lvalue is an expression that refers to an object. Easily, lvalue is the left value of an assignment expression;

Body is the realization of a function;

Scope is a program's area where name is known.

[ Program's Structure ]
Below is the structure of a main program written in C:

/* File name: ... */ /* Writer / programmer's name */ /* Short description of the program */ <type> main([int argc, char ** argv[,char ** envp]]) /* explanation of the program */ /* DICTIONARY */ /* Algorithm */ return (<retval>);

Actually there is no such a strict role in the matter of character's position.
For more clear example, it will be written here in my next post as I will keep posting about C. :D
Thank you for coming.
