You have seen a basic structure of pascal program, so it will be easy to understand other basic building blocks of the pascal programming language.
Variables
A variable definition is put in a block beginning with a var keyword, followed by definitions of the variables as follows:
Pascal variables are declared outside the code-body of the function which means they are not declared within the begin and end pairs, but they are declared after the definition of the procedure/function and before the begin keyword. For global variables, they are defined after the program header.
Functions/Procedures
In Pascal, a procedure is set of instructions to be executed, with no return value and a function is a procedure with a return value. The definition of function/procedures will be as follows −
Comments
The multiline comments are enclosed within curly brackets and asterisks as (* .. *). Pascal allows single-line comment enclosed within curly brackets { .. }.
Case Sensitivity
Pascal is a case non-sensitive language, which means you can write your variables, functions and procedure in either case. Like variables A_Variable, a_variable and A_VARIABLE have same meaning in Pascal.

Pascal Statements
Pascal programs are made of statements. Each statement specifies a definite job of the program. These jobs could be declaration, assignment, reading data, writing data, taking logical decisions, transferring program flow control, etc.
For example −
Reserved Words in Pascal
The statements in Pascal are designed with some specific Pascal words, which are called the reserved words. For example, the words, program, input, output, var, real, begin, readline, writeline and end are all reserved words.
Following is a list of reserved words available in Pascal.
| and | array | begin | case | const |
| div | do | downto | else | end |
| file | for | function | goto | if |
| in | label | mod | nil | not |
| of | or | packed | procedure | program |
| record | repeat | set | then | to |
| type | until | var | while | with |
Character set and Identifiers in Pascal
The Pascal character set consists of −
All upper case letters (A-Z)
All lower case letters (a-z)
All digits (0-9)
Special symbols - + * / := , . ;. () [] = {} ` white space
The entities in a Pascal program like variables and constants, types, functions, procedures and records, etc., have a name or identifier. An identifier is a sequence of letters and digits, beginning with a letter. Special symbols and blanks must not be used in an identifier. Antares auto tune website.

| Usage | |
Dev-C++ is a free full-featured integrated development environment (IDE) distributed under the GNU General Public License for programming in C and C++. It is written in Delphi.
It is bundled with, and uses, the MinGW or TDM-GCC 64bit port of the GCC as its compiler. Dev-C++ can also be used in combination with Cygwin or any other GCC-based compiler.[1]
Dev Pascal Compiler
Dev-C++ is generally considered a Windows-only program, but there are attempts to create a Linux version: header files and path delimiters are switchable between platforms.
Devpaks[edit]
An additional aspect of Dev-C++ is its use of DevPaks: packaged extensions on the programming environment with additional libraries, templates, and utilities. DevPaks often contain, but are not limited to, GUI utilities, including popular toolkits such as GTK+, wxWidgets, and FLTK. Other DevPaks include libraries for more advanced function use. Users of Dev-C++ can download additional libraries, or packages of code that increase the scope and functionality of Dev-C++, such as graphics, compression, animation, sound support and many more. Users can create Devpaks and host them for free on the site. Also, they are not limited to use with Dev-C++ - the site says 'A typical devpak will work with any MinGW distribution (with any IDE for MinGW)'.
Development status[edit]
From February 22, 2005 to June 2011 the project was not noticeably active, with no news posted nor any updated versions released. In a 2006 forum post, lead developer Colin Laplace stated that he was busy with real-life issues and did not have time to continue development of Dev-C++.[2]
There are two forks of Dev-C++ since then: wxDev-C++ and the Orwell version.
wxDev-C++ is a development team that has taken Dev-C++ and added new features such as support for multiple compilers and a RAD designer for wxWidgets applications.
On June 30, 2011 an unofficial version 4.9.9.3 of Dev-C++ was released by Orwell (Johan Mes), an independent programmer,[3] featuring the more recent GCC 4.5.2 compiler, Windows' SDK resources (Win32 and D3D), numerous bugfixes, and improved stability. On August 27, after five years of officially being in a beta stage, version 5.0 was released.[4] This version also has its own separate SourceForge[5] page since version 5.0.0.5, because the old developer isn't responding to combining requests. On July 2014, Orwell Dev-C++ 5.7.1 was released featuring the more recent GCC 4.8.1 which supports C++11.
Notable uses[edit]
On May 4, 2015, The Singapore Prime Minister Lee Hsien Loong posted his Sudoku solver program in C++ on Facebook. In his screen shot, he's using Microsoft Windows and Dev-C++ as his IDE.[6]
