C

The C programming language is a high-level programming language. C is a staple in application development, along with its successors C++ and C#. The C language is considered one of the fastest programming languages. C files end in .c, but there are some custom files that use a different ending.

Overview

C is a very powerful language that can do a lot. In this introduction, we will go over how to make your program, how to run it, and where to learn more.

Your first program

Using any text editor, create a new file called "main.c". Inside, paste the following code:

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

STDIO.h is sort of like a hidden file. It stands for STandarD Input Output.

C compilation

MacOS

On MacOS, the C compiler comes pre-installed on the terminal. Depending on your version, you can use the command

gcc -o main main.c

or

clang -o main main.c

Run it by typing in ./main

Other

There is no official C compiler to use. Instead, you must download one from GNU or a similar source. There is also a C extension in VS Code Desktop.

Learning more

Many websites such as Learn C and W3Schools offer C courses that are easy to follow.
