Begin Your Journey with C

To initiate your learning in C, you require the following:

  • A text editor for crafting C code
  • A compiler like GCC to convert the C code into a machine-understandable language

There are various text editors and compilers to select from. For this tutorial, an IDE (Integrated Development Environment) will be used by us.

Setting up the C IDE

An IDE is a software suite that consolidates the basic tools needed to write and test the code. Popular IDEs include Code::Blocks, Eclipse, and Visual Studio which are all free to use and facilitate both the editing and debugging of C code.

Note: Although web-based IDEs can be used, they typically have more limitations compared to their desktop counterparts.

We recommend starting with Code::Blocks. The latest version can be downloaded from here.

Let's Start with C

Create your first C file by following the steps below:

  1. Open Codeblocks
  2. Go to File > New > Empty File
  3. Write the following C code and save the file as myfirstprogram.c:
#include <stdio.h>, int main() { printf("Welcome to Fynd Academy!"); return 0;}

The above code might seem incomprehensible for now, we'll break it down in later chapters. For now, concentrate on running the code.

Executing Your Code

After writing the code, it's time to run it. In Codeblocks, navigate to Build > Build and Run. Your result will look something like this:

Welcome to Fynd Academy!

Great job! You've just written and executed your first C program.

Your C Learning Journey with Fynd Academy

Learning C with Fynd Academy is facilitated by our "Practice it Yourself" tool. It concurrently illustrates the code and the outcome, simplifying every new part you learn:

#include <stdio.h>int main() { printf("Welcome to Fynd Academy!"); return 0;} Welcome to Fynd Academy!

<p>C Pointers</p> <p>Creating Pointers</p> <p>In previous lessons, it was discussed that we can get the memory address of a variable with the reference operator &:</p> <p>Example</p> <pre> int userAge = 43; printf("%d", userAge); printf("%p", &userAge); </pre> <p>A pointer is a variable that stores the memory address of another variable as its value. A pointer variable points to a data type (like int) of the same type, and is created with the * operator. The address of the variable you are working with is assigned to the pointer:</p> <p>Example</p> <pre> int userAge = 43; int* ptr = &userAge; printf("%d\n", userAge); printf("%p\n", &userAge); printf("%p\n", ptr); </pre> <p>Example explained:</p> <p>Create a pointer variable with the name ptr, that points to an int variable (userAge). Note that the type of the pointer has to match the type of the variable you're working with (int in our example).</p> <p>Use the & operator to store the memory address of the userAge variable, and assign it to the pointer. Now, ptr holds the value of userAge's memory address.</p> <p>Dereference</p> <p>In the example above, we used the pointer variable to get the memory address of a variable. You can also get the value of the variable the pointer points to, by using the * operator (the dereference operator):</p> <p>Example</p> <pre> int userAge = 43; int* ptr = &userAge; printf("%p\n", ptr); printf("%d\n", *ptr); </pre> <p>Note that the * sign can be confusing here, as it does two different things in our code:</p> <ol> <li>When used in declaration (int* ptr), it creates a pointer variable.</li> <li>When not used in declaration, it acts as a dereference operator.</li> </ol> <p>Good To Know: There are two ways to declare pointer variables in C:</p> <pre> int* myNum; int *myNum; </pre> <p>Notes on Pointers</p> <p>Pointers make C stand out from other programming languages, like Python and Java. They allow us to manipulate the data in the computer's memory. This can reduce the code and improve the performance. Pointers are especially useful for implementing data structures like lists, trees, and graphs. However, pointers must be handled with care, since it is possible to damage data stored in other memory addresses.</p> <p>C Exercises</p> <p>Test Yourself With Exercises</p> <p>Exercise:</p> <p>Create a pointer variable called ptr, that points to the int variable userAge:</p> <pre> int userAge = 43; ptr = &userAge; </pre> <p>Start the Exercise</p> <p>Pathfinder</p> <p>Track your progress - it's free!</p>
