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!

Moreover, a format specifier has to be used inside the printf() function for its presentation: <p> <br> <b>Example</b> <p> &lt;!-- Create variables --&gt;<br> &lt;?php<br> &nbsp;&nbsp;&nbsp;&nbsp; $variableOne = 5; <!-- Integer (whole number) --> <br> &nbsp;&nbsp;&nbsp;&nbsp; $variableTwo = 5.99; <!-- Floating point number --> <br> &nbsp;&nbsp;&nbsp;&nbsp; $variableThree = 'D'; <!-- Character --> <br> &lt;!-- Print variables --&gt;<br> &nbsp;&nbsp;&nbsp;&nbsp; printf("%d&lt;br&gt;", $variableOne);<br> &nbsp;&nbsp;&nbsp;&nbsp; printf("%f&lt;br&gt;", $variableTwo);<br> &nbsp;&nbsp;&nbsp;&nbsp; printf("%c&lt;br&gt;", $variableThree); &lt;?php&gt;<br> </p> <br> <h2>Fundamental Data Structures</h2> <br> The data type defines the size and type of data the variable can accommodate. In this guide, we would focus exclusively on the most elementary ones: <table> <tr><th>Data Type </th><th>Size </th><th>Description </th><th>Example </th></tr> <tr><td>int</td><td>2 or 4 bytes</td><td>Can store full numbers, devoid of decimals</td><td>1</td></tr> <tr><td>float</td><td>4 bytes</td><td>Can store fractional numbers, containing minimum of one decimal. Enough for storing 6-7 decimal digits.</td><td>1.99</td></tr> <tr><td>double</td><td>8 bytes</td><td>Can store fractional numbers, containing minimum of one decimal. Enough for storing 15 decimal digits</td><td>1.99</td></tr> <tr><td>char</td><td>1 byte</td><td>Can store a singular character/letter/number, or ASCII values</td><td>'A'</td></tr> </table> <br> <h2>Fundamental Format Specifiers</h2> <br> There are different format specifiers for each data type. Here are a few: <table> <tr><th>Format Specifier </th><th>Data Type </th></tr> <tr><td>%d or %i</td><td>int</td></tr> <tr><td>%f or %F</td><td>float</td></tr> <tr><td>%lf</td><td>double</td></tr> <tr><td>%c</td><td>char</td></tr> <tr><td>%s</td><td>Used for strings (text), which will be explained in an upcoming section</td></tr> </table> <h2>C Hand-On Experience</h2> <p> <b>Exercise:</b> Assign the appropriate data type for the following variables: <p> $variableOne = 5;<br> $variableTwo = 5.99;<br> $variableThree = 'D'; <p> <br> <Button>Submit Answer</Button> <Button>Start the Exercise</Button> <br> <h2>Fynd Academy</h2> Your progress is valuable. <p> <br>
