In this walkthrough, you create a basic, Hello, World style C program by using a text editor, and then compile it on the command line. If youd like to try the Visual Studio IDE instead of using the command line, see Walkthrough Working with Projects and Solutions C or Using the Visual Studio IDE for C Desktop Development. In this walkthrough, you can use your own Visual C program instead of typing the one thats shown, or you can use a Visual C code sample from another help article. To complete this walkthrough, you must have installed either Visual Studio and the optional Visual C components, or the Microsoft Visual C Build Tools. Visual Studio is a powerful integrated development environment that supports a full featured editor, resource managers, debuggers, and compilers for many languages and platforms. For information on these features and how to download and install Visual Studio, including the free Visual Studio Community edition, see Visual. Studio. com. The Microsoft Visual C Build Tools installs only the command line compiler, tools, and libraries you need to build C and C programs. Its perfect for build labs or classroom exercises and installs relatively quickly. To install only the command line tools, download and install Microsoft Visual C Build Tools 2. Before you can build a C or C program on the command line, you must verify that the tools are installed, and that you can access them from the command line. Visual C has complex requirements for the command line environment in order to find the tools, headers, and libraries it uses. You cant use Visual C in a plain command prompt window. Fortunately, Visual C installs shortcuts for you to launch a developer command prompt that has the environment set up for command line builds. Unfortunately, the names of the developer command prompt shortcuts and where they are located are different in almost every version of Visual C and on different versions of Windows. Your first walkthrough task is finding the right one to use. Note. A developer command prompt shortcut automatically sets the correct paths for the compiler and tools, and for any required headers and libraries. You must set these environment values yourself if you use a regular Command Prompt window. For more information, see Setting the Path and Environment Variables for Command Line Builds. We recommend you use a developer command prompt shortcut instead of building your own. Open a developer command prompt. If you have installed Visual Studio 2.

There may be differences in the current directory or version numbers, depending on the version of Visual C and any updates installed. If this is similar to what you see, then you are ready to build C or C programs at the command line. Note. If you get an error such as cl is not recognized as an internal or external command, operable program or batch file, error C1. LNK1. 10. 4 when you run the cl command, then either you are not using a developer command prompt, or something is wrong with your installation of Visual C. You must fix this issue before you can continue. If you cant find the developer command prompt shortcut, or if you get an error message when you enter cl, then your Visual C installation may have a problem. Try reinstalling the Visual C component in Visual Studio, or reinstall the Microsoft Visual C Build Tools. Dont go on to the next section until this works.

LNK1. 10. 4, your developer command prompt is not set up correctly. C Program Structure. Before we study basic building blocks of the C programming language, let us look at a bare minimum C program structure so that we can take it as a reference in upcoming chapters. Creating Hello World Program. A C program consists of the following parts Namespace declaration. A class. Class methods. Class attributes. A Main method. Statements and Expressions. Comments. Let us look at a simple code that prints the words Hello World. Hello. World. Application. Hello. World. static void Mainstring args. C. Console. Write. LineHello World. Console. Read. Key. When this code is compiled and executed, it produces the following result. Let us look at the various parts of the given program The first line of the program using System the using keyword is used to include the System namespace in the program. A program generally has multiple using statements. The next line has the namespace declaration. A namespace is a collection of classes. The Hello. World. Application namespace contains the class Hello. World. The next line has a class declaration, the class Hello. World contains the data and method definitions that your program uses. Classes generally contain multiple methods. Methods define the behavior of the class. However, the Hello. World class has only one method Main. The next line defines the Main method, which is the entry point for all C programs. The Main method states what the class does when executed. The next line. is ignored by the compiler and it is put to add comments in the program. The Main method specifies its behavior with the statement Console. Write. LineHello World Write. Line is a method of the Console class defined in the System namespace. This statement causes the message Hello, World to be displayed on the screen. The last line Console. Read. Key is for the VS. NET Users. This makes the program wait for a key press and it prevents the screen from running and closing quickly when the program is launched from Visual Studio. NET. It is worth to note the following points C is case sensitive. All statements and expression must end with a semicolon. The program execution starts at the Main method. Unlike Java, program file name could be different from the class name. Compiling and Executing the Program. If you are using Visual Studio. Net for compiling and executing C programs, take the following steps Start Visual Studio. Huawei B315s-22 Update'>Huawei B315s-22 Update. On the menu bar, choose File New Project.
