How to Write and Run a Program in C Compiler: A Beginner’s Guide

Learning how to write and run a C program can be quite intimidating for beginners. However, it can be a rewarding experience and opens up a world of opportunities for those who persevere. C is one of the oldest and most widely used programming languages, with applications ranging from operating systems to game development. In this beginner’s guide, we’ll take you through the basics of writing and running a program in C compiler.

What is C Compiler?
Compiler is a program that translates the human-readable code into machine-readable code. C compiler is a program that translates C source code into machine code or object code. In order to write and run a C program, you need a C compiler installed on your computer. There are several C compilers available such as GCC, Clang, and Microsoft Visual C++, among others.

Steps for Writing and Running a C Program
1. Install a C Compiler: As mentioned earlier, you need a C compiler installed on your computer. You can download and install a C compiler based on your operating system.
2. Choose a Text Editor: C source code is usually written in a text editor. You can choose any text editor like Notepad, Sublime, VS Code, or any other that supports C syntax highlighting.
3. Write the Code: Once you have your C compiler installed and a text editor set up, you can start writing your C code. A simple C program consists of main() function which is the entry point of the program.
4. Save the Code: Once you have written the code, save it with a .c extension.
5. Compile the Code: After saving the code, you need to compile it using a C compiler. Open the command prompt or terminal and navigate to the directory where the code is saved. Type the command to compile the code, giving the name of the source code file as an argument.
6. Run the Program: If the compilation was successful, you should now have an executable file generated by the compiler. Run the executable file by typing its name in the command prompt or terminal.

Here’s a sample code for a simple C program:

#include
int main() {
printf(“Hello World!”);
return 0;
}

This program prints “Hello World!” on the console.

Conclusion
Writing and running a program in C can be a challenging task for beginners, but it’s not an impossible feat. With a C compiler, a text editor, and the basics of C programming, you can write and run simple C programs. As you progress, you’ll learn more advanced concepts and be able to write complex programs. Keep practicing, and you’ll soon become proficient in writing and running C programs.
