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's the revised text as per your requirements: <h2>C For Loop</h2> <h3>For Loop</h3> For specific repetition of block of code, usage of the <i>for loop</i> is more suitable. <h3>Syntax</h3> <code> for (expression_A; expression_B; expression_C) {   // code block in ACTION } </code> Here, Expression_A is initiated before the code block's execution.<br/> Expression_B bespeaks the criterion to run the code block.<br/> Expression_C comes into action post execution of the code block. To delineate, look at the instance below which prints numbers ranging from 0 to 4: <h3>Sample</h3> <code> int indexValue; for (indexValue = 0; indexValue < 5; indexValue++) { printf("%d\n", indexValue);} </code> <h3>Above Sample Explained</h3> Expression_A initializes a variable prior to beginning of the loop (int indexValue = 0).<br/> Expression_B specifies the criterion for loop run (indexValue must be less than 5). The loop continues while this condition is true, else it terminates.<br/> Expression_C increments a value (indexValue++) each time the code block has been executed during the loop. <h3>C Drills</h3> <h4>Test Yourself With Drills</h4> Drill:<br/> Use a for loop to print "Yes" 5 times: <code> (int indexValue = 0; indexValue < 5; indexValue++) { printf("Yes\n"); } </code> <h3>Practice More!</h3> Fynd Academy
