    C Language: 1.1 Introduction

    • Procedural programming
    • Top-down program design

    C++ Language: 1.1 Introduction

    • Object-based programming (classes, objects, encapsulation, operator overloading)
    • Object-Oriented Programming (OOP): inheritance, polymorphism
    • Generic programming (class templates, function templates)

    1.1 Introduction – First Program: Printing a Line of Text

    • Includes iostream to enable input and output to screen
    • Uses cout stream object for displaying output: std::cout << "Welcome to C++ Programming." << endl;

    1.1 Introduction – Data Types

    • Data types and their sizes (in bytes): long double, double, float, unsigned long long int, long long int, etc.

    1.1 Introduction – Operator Precedence

    • Operator list with their precedence levels and associativity (left-to-right or right-to-left)

    1.1 Introduction – Control Structures

    • Selection statements (if, if-else, switch), repetition statements (for, while, do...while)

    1.1 Introduction – Arrays

    • Array declaration, element access, and examples of 1D and 2D arrays

    1.1 Introduction – Allocation and Deallocation

    • Dynamic memory allocation using new and deallocation using delete
    • Example programs Demonstrating allocation and deallocation

    1.2 C++

    • Improvements over C
    • Object-oriented capabilities
    • Superset of C

    1.3 A Simple Program: Adding Two Integers

    • Input/Output in C++: streams of characters (input and output)
    • Output streams examples using std::cout
    • Input streams examples using std::cin

    1.3 A Simple Program (continued)

    • Stream manipulators like std::endl (end-line) for newlines or format strings
    • Using namespaces (like std) to avoid naming conflicts
    • Cascading operations (using several << in a single statement)

    1.4 C++ Standard Library

    • Building C++ programs using its functions and classes
    • How to use the C++ standard library

    1.5 Header Files

    • Header files organize standard library functions, classes, etc.
    • How to use header files in programs

    1.6 Inline Functions

    • Inlining functions for increased speed (though can increase code size)
    • Using inline keyword to suggest inlining

    1.7 References and Reference Parameters

    • Pass by value vs. pass by reference
    • References as aliases that affect originals directly
    • Dangling references: references to variables that no longer exist
    • Multiple references: like pointers

    1.8 Empty Parameter Lists

    • void keyword for functions without parameters

    1.9 Default Arguments

    • Using default values for function parameters

    1.10 Unary Scope Resolution Operator (::)

    • Accessing global variables if local variables have the same name

    1.11 Function Overloading

    • Overloaded functions share the same name but have different argument lists (number, types)
    • Enables similar actions with different data types
    • Compiler manages overload resolution

    1.12 Function Templates

    • Templates for generic code reusable across different data types
    • Syntax, type parameters (typename or class) and usage
