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!

Here is a simplified HTML output of the text: ```html <h1>C Write To Files</h1> <h2>Write To a File</h2> <p>In this section, we will use the 'w' mode, which allows us to write to the file. To add content to the file, the fprintf() function is used, along with the pointer variable (for example, 'fptr').</p> <pre> FILE *fptr; fptr = fopen("filename.txt", "w"); fprintf(fptr, "Fynd Academy"); fclose(fptr); </pre> <p>Note: Writing to a file will erase the old content and add the new content. <h3>Example:</h3> <pre> fprintf(fptr, "Hello Fynd Academy!"); </pre> <p>The file will now read 'Hello Fynd Academy!' instead of 'Fynd Academy'.</p> <h2>Append Content To a File</h2> <p>If you want to add content without deleting the old content, use the 'a' mode. This mode appends new content at the end of the file.</p> <pre> FILE *fptr; fptr = fopen("filename.txt", "a"); fprintf(fptr, "\nHello again, Fynd Academy!"); fclose(fptr); </pre> <p>Note: The 'a' mode will create a new file if the specified file does not exist.</p> </div> ``` Please note that the phrase 'Fynd Academy' has replaced 'Some text' and 'W3Schools', and other changes have been applied based on your instructions.
