Programming For Problem Solving - BHAJAN GYAN EDUCATION

Introduction to Programming:- Unit: 1
C is a powerful and widely-used programming language known for its efficiency and versatility. It was developed in the early 1970s by Dennis Ritchie at Bell Labs for system programming. Since then, C has become one of the most popular languages for developing software applications, operating systems, and embedded systems.

Arithmetic Expressions and Precedence: Unit 1
Arithmetic Operators:- Addition (+), Subtraction (-), Multiplication (*), Division (/), Modulus (%) Operator Precedence:- Operator precedence determines the order in which operations are performed in an expression. Operators with higher precedence are evaluated before those with lower precedence.

Arrays: Unit :- 2
Arrays in C are a collection of elements of the same data type, stored in contiguous memory locations. They are used to store multiple values in a single variable, making it easy to manage and manipulate large sets of data.

Basic Algorithms:- Unit:- 2
1. Linear Search 2. Binary Search Sorting 3. Bubble Sort 4. Insertion Sort 5. Selection Sort

Function: Unit:- 3
a function is a self-contained block of code that performs a specific task. Functions help to organize code, make it more readable, and facilitate code reuse.

Recursion: Unit:- 3
Recursion is a programming technique where a function calls itself directly or indirectly. It allows problems to be solved in a more straightforward and elegant way by breaking them down into smaller, more manageable sub-problems. In C language, recursion is commonly used in tasks such as sorting, searching, and working with data structures like trees and graphs.

Structure:- Unit : 4
n C programming, a function is defined as a self-contained block of code designed to perform a specific task. It encapsulates a series of statements that execute sequentially when the function is called. Functions in C typically have a return type, a name, optional parameters (arguments), and a body enclosed within curly braces. They are essential for modularizing code, promoting reusability, and enhancing program organization and readability.

Pointers:- Unit: 4
In C programming language, a pointer is a variable that stores the memory address of another variable. It allows direct manipulation of memory locations, enabling efficient access and manipulation of data stored in memory. Pointers are used extensively for dynamic memory allocation, passing addresses to functions, and implementing data structures like linked lists and trees. They are a fundamental feature of C, providing powerful capabilities but also requiring careful management to avoid errors like segmentation faults or memory leaks.

File Handling: Unit : 4
File handling in C language refers to the process of working with files stored on the computer's storage devices, such as reading from them, writing to them, or modifying their contents. It involves using functions and operations provided by the C standard library, particularly , to interact with files. File handling in C typically includes operations like opening files, reading data from files, writing data to files, closing files, and handling errors that may occur during these operations. This allows programs written in C to store and retrieve data persistently, making it a fundamental aspect of many C applications, ranging from simple text file operations to complex database interactions.
