Overview of c++

1. Introduction to C++
Programming Language
A Journey into Object-Oriented
Programming

2. What is Programming?
• Programming is the process of designing and
building executable computer programs to
accomplish a specific computing task.
• Purpose: Solve problems, automate tasks,
create software and applications.

3. What is C++?
• C++ is a high-level, general-purpose
programming language created by Bjarne
Stroustrup in 1985.
• Key Feature: Adds object-oriented
programming to C.

4. Features of C++
• Simple and modular
• Machine Independent
• Low-level access
• Fast execution
• Object-Oriented

5. Applications of C++
• Game engines
• Web browsers
• Operating systems
• Embedded systems
• Financial systems

6. Why Learn C++?
• Strong foundation in programming
• Popular in industry
• Fast execution
• Familiar syntax (similar to C, Java, C#)
• Supports both low- and high-level
programming

9. Basic Syntax & Structure of C++
• #include <iostream>
• using namespace std;
• int main() {
• cout << "Hello, World!";
• return 0;
• }

10. Variables in C++
• A variable is a name given to a memory
location.
• Example: int age = 25;
• Types: int, float, char, string, bool

11. Data Types in C++
• Basic Types: int, float, char, double, bool
• Derived Types: arrays, pointers
• User-defined Types: class, struct, union

12. Control Structures
• Conditional: if, else if, else, switch
• Loops: for, while, do-while
• Example:
• for(int i = 0; i < 5; i++) {
• cout << i << " ";
• }

13. Functions in C++
• Definition: A function is a reusable block of
code.
• Example:
• int add(int a, int b) {
• return a + b;
• }

14. Hands-on Activity: Basic Calculator
• Goal: Implement a simple calculator using functions
• Operations: Add, Subtract, Multiply, Divide
• float calculate(float a, float b, char op) {
• switch(op) {
• case '+': return a + b;
• case '-': return a - b;
• case '*': return a * b;
• case '/': return a / b;
• default: return 0;
• }
• }
