How To Execute A C Program In Terminal

C is one of the most powerful programming languages. You can create simple programs written in C using free C build tools and compilers that are available for the different operating systems like Windows, iOS, and Android. It has many pre-defined variables, functions, and libraries. Using a fast and reliable C++ compiler for Windows is very important for beginners and professionals since it helps C++ developers in remembering which language features exist, how to use them, and even detect errors when we get it wrong.

You can run a C program using the C or C++ compilers and build tools included with C++ Builder. C++ Builder has a free C++ Builder Community Edition as well as commercial C++ Builder Professional / Architect / Enterprise Versions with more extensive capabilities suitable for those who wish to go further with development or who do not fall within the restrictions of the Community Edition license terms.

As a C++ compiler, I believe the best professional C++ IDE and code editor to implement C++ Programs for Windows, iOS and Android is the latest version of RAD Studio or C++ Builder,

If you are new to programming, here is a quick introduction on how to create a simple C Program. C Programs (C code) is a text file, which means you can use any editor to edit these kinds of programs such as Notepad, Notepad++ and so on but a proper C++ IDE has much more dedicated features to edit and run C Programs. Suitable IDEs include Dev-C++, RAD Studio, and C++ Builder.

Before we get started, you should download and install a free C and C++ compiler and IDE.

How To Execute A C Program In Terminal A hello World C program

When you start coding, first of all, you should include any libraries that you are going to use. Generally, for beginners stdio.h library is enough to do simple beginner apps. We can include this library as below,

Second, you should add the main procedure (the main program, the main function) as below,

After that you should write your programming code lines into this procedure, between { and } brackets. If you are a beginner “Hello World” examples are good to understand feature of that programming language. It is good to understand how to edit text, how to write in its format, how to compile and link, how to debug and execute, how to deploy or release. This full example below is a “Hello World” C example that can be run with C++ Builder.

In C and C++, after every command you use you should put ; to the end of your commands. In this example above we print a text with printf() function and then we wait to get a character input (key press) with getchar(); functions, then we exit and return 0; which means our main app successfully run and exit.
