Dev C++ Basic Syntax

  1. Welcome to the Svelte tutorial. This will teach you everything you need to know to build fast, small web applications easily. You can also consult the API docs and the examples, or — if you're impatient to start hacking on your machine locally — the 60-second quickstart.
  2. Bloodshed Dev-C is a full-featured Integrated Development Environment (IDE) for the C/C programming language. It uses Mingw port of GCC (GNU Compiler Collection) as it's compiler. Dev-C can also be used in combination with Cygwin or any other GCC based compiler.

C is a general purpose language language, when I say general purpose it simply means that it is designed to be used for developing applications in a wide variety of domains. C Tutorial. To learn C programming, refer these tutorials in the given order.

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.

Why to Learn C++

C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:

  • C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.

  • C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.

  • C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.

  • C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.

  • C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.

There are 1000s of good reasons to learn C++ Programming. But one thing for sure, to learn any programming language, not only C++, you just need to code, and code and finally code until you become expert.

Just to give you a little excitement about C++ programming, I'm going to give you a small conventional C++ Hello World program, You can try it using Demo link

C++ is a super set of C programming with additional implementation of object-oriented concepts.

There are many C++ compilers available which you can use to compile and run above mentioned program:

Dev C Basic Syntax Examples

  • Apple C++. Xcode

  • Bloodshed Dev-C++

  • Clang C++

  • Cygwin (GNU C++)

  • Mentor Graphics

  • MINGW - 'Minimalist GNU for Windows'

  • GNU CC source

  • IBM C++

  • Intel C++

  • Microsoft Visual C++

  • Oracle C++

  • HP C++

It is really impossible to give a complete list of all the available compilers. The C++ world is just too large and too much new is happening.

Applications of C++ Programming

As mentioned before, C++ is one of the most widely used programming languages. It has it's presence in almost every area of software development. I'm going to list few of them here:

  • Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.

  • Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.

  • Computation Programming - C++ is the best friends of scientists because of fast speed and computational efficiencies.

  • Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines.

  • Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.

This list goes on, there are various areas where software developers are happily using C++ to provide great softwares. I highly recommend you to learn C++ and contribute great softwares to the community.

Audience

This C++ tutorial has been prepared for the beginners to help them understand the basic to advanced concepts related to C++.

Prerequisites

Before you start practicing with various types of examples given in this C++ tutorial,we are making an assumption that you are already aware of the basics of computer program and computer programming language.

C++ is a popular programming language because it’s powerful, fast, easy to use, standardized, and more. Whether you are new to C++ programming or an advanced user, check out the following information on C++ mistakes, header files, and syntax. All information pertains to Windows, Mac, and Linux computers.

The 10 Most Common C++ Mistakes

Although many C++ programmers take measures to prevent bugs, mistakes still slip through. This list of the ten most common mistakes while writing C++ code can help both new and veteran programmers:

  1. You forgot to declare the variable.

  2. You used the wrong uppercase and lowercase letters; for example, you typed Main when you meant main.

  3. You used one equal sign (=) when you were supposed to use two (), either in an if statement or in a for loop.

  4. You forgot #include <iostream> or using namespace std;.

  5. You dropped the laptop in the swimming pool.

  6. You forgot to call new and just started using the pointer anyway.

  7. You forgot the word public: in your classes so everything turned up private.

  8. You let the dog eat the remote.

  9. You forgot to type the parentheses when calling a function that takes no parameters.

  10. You forgot a semicolon, probably at the end of a class declaration.

The Usual C++ Header Files

In C++, a header file holds forward declarations of identifiers. Here are some of the most common C++ header files that you’ll be using, along with their correct spellings. These aren’t by any means all of them, but they are the most common:

  • Include <string> if you’re going to be using the string class.

  • Include <iostream> when you want to use cout and cin.

  • Include <fstream> when you want to read or write files.

  • Include <iomanip> if you want advanced manipulator usage in your streams.

  • Include <stdlib.h> for general operations, including system(“PAUSE”).

C++ Syntax that You May Have Forgotten

Remembering a bunch of C++ syntax can make you “loopy.” The following samples show the syntax of some of the more easily forgotten C++ situations: a for loop, a while loop, and a switch statement; a class and the code for a member function; a base class and a derived class; a function, function pointer type, and pointer to the function; and a class template and then a class based on the template.

Here’s a for loop:

Here’s a while loop that counts from 10 down to 1:

And here’s a switch statement:

Here’s a class and the code for a member function:
