C Program to Add Two Numbers In this program, user is asked to enter two integers. Then, the sum of those two integers is stored in a variable and displayed on the screen. To add a class in a Visual Studio C project, in Solution Explorer, right-click the project, choose Add, and then choose Class. This opens the Add Class dialog box. When you add a class, you must specify a name that is different from classes that already exist in MFC or ATL. You need to compile the implementation files into object files and link them together. The following is an example for when you are using g: g -c class.cpp -o class.o g -c main.cpp -o main.o g class.o main.o -o main./main.
-->You can add a generic C++ class by using Class View. A generic C++ class is a class that you define or that is derived from a class that you define.
To add a generic C++ class to a project:
- In Class View, right-click the project to which you want to add the new class, choose Add, and then choose Class.
- In the Add Class dialog box, in the templates pane, select C++ Class. Select Add to display the generic C++ class wizard.
- In the wizard, provide a class name, and then define settings or accept the defaults.
- To close the wizard and view the new generic C++ class in the project, select Finish.

- Class nameSets the name of the new class.
- .h fileSets the name of the header file for the new class. By default, this name is based on the name you provide in Class name. To save the header file to the location of your choice, or to append the class declaration to an existing file, select the ellipsis button (...). If you specify an existing file and select Finish, the wizard prompts you to specify whether the class declaration should be appended to the file contents. To append the declaration, select Yes; to return to the wizard and specify another file name, select No.
- .cpp fileSets the name of the implementation file for the new class. By default, this name is based on the name you provide in Class name. To save the implementation file to the location of your choice, or to append the class definition to an existing file, select the ellipsis button (...). If you specify an existing file and select Finish, the wizard prompts you to specify whether the class definition should be appended to the file contents. To append the definition, select Yes; to return to the wizard and specify another file name, select No.
- Base classSets the base class for the new class.
- AccessSets access to the base class members for the new class. Access modifiers are keywords that specify the level of access that other classes have to the class member functions. For more information about how to specify access, see Member access control. By default, the class access level is set to
public
.public
protected
private
- Default (No access modifier is generated.)
- Virtual destructorSpecifies whether the class destructor is virtual. Use of a virtual destructor helps make sure that the correct destructor is called when instances of derived classes are deleted.
- InlineGenerates both the class constructor and the class definition as inline functions in the header file.
- ManagedWhen selected, adds a managed class and header file. When cleared, adds a native class and header file.

Local Environment Setup
If you are still willing to set up your environment for C++, you need to have the following two softwares on your computer.
Text Editor
This will be used to type your program. Examples of few editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi.
Name and version of text editor can vary on different operating systems. For example, Notepad will be used on Windows and vim or vi can be used on windows as well as Linux, or UNIX.
The files you create with your editor are called source files and for C++ they typically are named with the extension .cpp, .cp, or .c.

A text editor should be in place to start your C++ programming.
C++ Compiler
This is an actual C++ compiler, which will be used to compile your source code into final executable program.
Most C++ compilers don't care what extension you give to your source code, but if you don't specify otherwise, many will use .cpp by default.
Most frequently used and free available compiler is GNU C/C++ compiler, otherwise you can have compilers either from HP or Solaris if you have the respective Operating Systems.
Installing GNU C/C++ Compiler
UNIX/Linux Installation
If you are using Linux or UNIX then check whether GCC is installed on your system by entering the following command from the command line −
If you have installed GCC, then it should print a message such as the following −
If GCC is not installed, then you will have to install it yourself using the detailed instructions available at https://gcc.gnu.org/install/
Mac OS X Installation
If you use Mac OS X, the easiest way to obtain GCC is to download the Xcode development environment from Apple's website and follow the simple installation instructions.
Xcode is currently available at developer.apple.com/technologies/tools/.
Windows Installation
To install GCC at Windows you need to install MinGW. To install MinGW, go to the MinGW homepage, www.mingw.org, and follow the link to the MinGW download page. Download the latest version of the MinGW installation program which should be named MinGW-<version>.exe.

While installing MinGW, at a minimum, you must install gcc-core, gcc-g++, binutils, and the MinGW runtime, but you may wish to install more.
Add the bin subdirectory of your MinGW installation to your PATH environment variable so that you can specify these tools on the command line by their simple names.

When the installation is complete, you will be able to run gcc, g++, ar, ranlib, dlltool, and several other GNU tools from the Windows command line.
