Chapter 4: C++ - Programming Concepts

Welcome to the C++ Programming chapter. In this section, you will learn the basics of C++ programming, including syntax, data types, and how to solve logical problems using simple C++ programs.

Topics Covered:

  1. Introduction to C++
    • What is C++?
    • Features and applications of C++.
  2. Basic Syntax
    • Structure of a C++ program.
    • #include directives and the main() function.
  3. Variables and Data Types
    • Declaring variables.
    • Data types like int, float, char, etc.
  4. Input and Output
    • Using cin and cout.
  5. Control Statements
    • if, else, and switch statements.
  6. Loops
    • for, while, and do-while loops.
  7. Functions
    • Declaring and using functions in C++.

Practical Exercises:

Try these exercises to practice your C++ programming skills:

  1. Write a program to print “Hello, World!”.
  2. Create a program that calculates the sum of two numbers entered by the user.
  3. Write a program to find the largest of three numbers using if-else statements.
  4. Develop a program to display the multiplication table of a number using a for loop.
  5. Write a program to calculate the factorial of a number using a while loop.

Sample Code:

Here’s an example of a simple C++ program:

#include <iostream>
using namespace std;

int main() {
    int num1, num2, sum;
    
    cout << "Enter first number: ";
    cin >> num1;
    
    cout << "Enter second number: ";
    cin >> num2;
    
    sum = num1 + num2;
    cout << "The sum is: " << sum << endl;
    
    return 0;
}
