C Basics for Beginners

 Day - 3  Understanding C Memory Layout Memory in a C program is divided into different sections, each with a specific purpose, which helps the program run efficiently and manage data. Let's go through each section and explain its role with simple examples. 1. Text Segment (Code) This section contains the actual machine code, the instructions that tell the computer what to do. Example :  printf("Hello, World!"); Here, the compiled machine code for printf("Hello, World!"); will be stored in the text segment . It's read-only, so it can't be modified during runtime. 2. Initialized Data Segment This segment stores global and static variables that are initialized with a value before the program runs. Example :   int globalVar = 10 ;   static int staticVar = 5 ; Here, globalVar and staticVar are stored in the initialized data segment because they are global/static and have initial values. 3. Uninitialized Data Segment (BSS) This segment stores global an...

     Day - 2          Real-World Applications of C Simple Calculator : Concepts : Functions : To perform different operations like addition, subtraction, multiplication, and division. Control Structures : If-else statements to choose the operation based on user input. Text-Based Games : Concepts : Loops : To handle game turns or rounds. Arrays : For storing player scores or game states. Conditional Statements : To determine game outcomes (e.g., win/lose conditions). Basic File Operations : Concepts : File I/O : Reading from and writing to text files, which can be useful for saving user data or game scores. Strings : Manipulating strings for file names and content. Student Record Management System : Concepts : Structs : To define a student record (name, age, grades). Arrays of Structs : To manage multiple student records. Basic File I/O : To save and retrieve records from a file. Tic-Tac-Toe Game : Concepts : 2D Arrays : To represent the game boa...

 Day - 1 What is C Programming? Why Use C? Key Features of C Real-World Applications of C Why C is Perfect for Beginners Introduction to C Programming What is C Programming? C programming is a powerful, efficient, and straightforward programming language that has been around for decades and continues to be widely used today. Originally developed in the 1970s by Dennis Ritchie at Bell Labs, C was designed to help with system programming, specifically for writing operating systems like UNIX. Its simplicity, speed, and versatility quickly made it popular among programmers, and it’s now considered a foundational language in the programming world. Why Use C? One of the main reasons to learn C is its influence on many modern languages like C++, Java, Python, and others. By learning C, beginners gain a strong understanding of basic programming concepts, such as loops, conditions, functions, and memory management, that carry over to other languages. C also helps programmers understand how...
