How can I write and run my first C program?

To write and run your first C program after installing the compiler, you can start by opening a text editor or IDE. Create a new file and save it with a .c extension, for instance, hello.c. In the editor, write a simple C program like this:
“`c

include

int main() {
printf(“Hello, World!\n”);
return 0;
}
“`
Once you’ve written the code, save the file.

If you’re using a command-line interface, navigate to the directory where the file is saved and compile the program by running gcc hello.c -o hello. This command will create an executable file called hello. You can then run the program by typing ./hello on macOS/Linux or hello.exe on Windows. If everything is set up correctly, you should see the output “Hello, World!” in your terminal.

What are some common mistakes to avoid when installing C programs?

One common mistake is failing to set the PATH environment variable correctly after installing a C compiler like MinGW. This step is crucial as it allows your command line to recognize compiler commands such as gcc. Make sure to double-check that the bin folder is included in your system PATH. If not, you will encounter command not found errors when attempting to compile your code.

Another mistake is not installing necessary dependencies or libraries for more advanced C programming. While starting with basic C programs is okay, as you progress, you might require additional packages or libraries to enable certain functionalities. Always refer to the documentation for your chosen IDE or compiler so you can install any required libraries right from the start.
