Introduction to Programming

What is Programming?

The design and development of software programs

A programming language is a formal language which follows a set of rules (syntax) to describe the behaviour of the program.

Common languages you may have heard of are:
Python, JavaScript, C, C#, C++, .NET

We will be learning C in this course!

What is C

C is a general-purpose programming language used to write software.

It is used very commonly!
In fact all the major operating systems (Windows, Mac, and Linux) are written in C!

What can C offer?

#include <stdio.h>

int main(void) {
    int number = 5;                 // C offers variables!
    number = 5 * 2;                 // C offers maths!

    if (number == 10) {             // C offers conditions!
        printf("5 x 2 is 10");      // C offers output!
    } else {
        printf("5 x 2 is not 10!");
    }

    return 0;
}

And lots more!

C Code Files

Source code files for programs written in C usually have a .c file extension.
Ultimately, all source code files are just text documents that can be edited with any text editor.
