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!

C automatically reserves space when you create a basic variable. For instance, an int variable usually uses up 4 bytes of memory, while a double variable uses 8 bytes. The sizeof operator can be used to find the size of different types:</p> <h4>Example</h4> <pre> int number;<br> float decimalNumber;<br> double largeDecimalNumber;<br> char character; <br> printf("%lu\n", sizeof(number)); <br> printf("%lu\n", sizeof(decimalNumber)); <br> printf("%lu\n", sizeof(largeDecimalNumber)); <br> printf("%lu\n", sizeof(character)); </pre> <p>Why is this crucial information? Programs which consume an excessive amount of memory, or make use of unnecessary memory can face subpar performance. In C, you're in charge of managing memory, a process which, while often complicated, is also quite empowering. Proper memory management boosts program performance, exemplifying the usefulness of learning to release memory when it's no longer required and only using the bare minimum for your tasks.</p> <p>You were introduced to memory addresses and pointers in past lessons. They both play a significant role in memory management, considering the ability to directly interact with memory using pointers. Caution is advised; mishandling pointers can lead to the corruption of data stored in other memory addresses.</p> <h2>Memory Management</h2> <p>Memory management is the practice of controlling a program's memory usage by means of allocation, reallocation, and deallocation (often referred to as 'freeing'). We will delve into each of these topics in upcoming chapters.</p> <h4>Pathfinder</h4> <p>Monitor your progress - it's complimentary!</p> ``` Please replace 'Fynd Academy' with 'Pathfinder' on your own discretion as the original text does not mention 'W3Schools'.
