# Introduction

Welcome to the world of C++ coding examples! In this article, we will explore practical examples that will help you enhance your programming skills and delve deeper into the wonders of C++ programming language. Whether you are a beginner or an experienced programmer, these examples will serve as a valuable resource to strengthen your understanding and proficiency in C++.

## C++ Coding Examples: Enhance Your Programming Skills with Practical Examples

Let’s jump right into some fascinating coding examples to demonstrate the power and versatility of C++.

### Example 1: Hello World

cpp

`#include <iostream>`

int main() {
std::cout << “Hello, World!” << std::endl;
return 0;
}

This classic “Hello, World!” example is the perfect starting point for any programming language. It showcases the basic structure of a C++ program, where we use the `cout` object from the `iostream` library to print the desired message on the console.

### Example 2: Arithmetic Operations

cpp

`#include <iostream>`

int main() {
int num1 = 10;
int num2 = 5;
int sum = num1 + num2;
int difference = num1 – num2;
int product = num1 * num2;
int quotient = num1 / num2;

std::cout << “Sum: “ << sum << std::endl;
std::cout << “Difference: “ << difference << std::endl;
std::cout << “Product: “ << product << std::endl;
std::cout << “Quotient: “ << quotient << std::endl;

return 0;
}

In this example, we perform basic arithmetic operations using C++. We declare two integer variables, `num1` and `num2`, and calculate their sum, difference, product, and quotient. The results are then displayed on the console using the `cout` object.

### Example 3: Conditional Statements

cpp

`#include <iostream>`

int main() {
int age;
std::cout << “Enter your age: “;
std::cin >> age;

if (age >= 18) {
std::cout << “You are eligible to vote!” << std::endl;
} else {
std::cout << “You are not eligible to vote yet.” << std::endl;
}

return 0;
}

This example demonstrates the usage of conditional statements in C++. We prompt the user to enter their age and then use an `if` statement to check if they are eligible to vote based on the entered age. The appropriate message is then displayed accordingly.

### Example 4: Loops

cpp

`#include <iostream>`

int main() {
for (int i = 1; i <= 5; i++) {
std::cout << “Iteration: “ << i << std::endl;
}

int count = 1;
while (count <= 5) {
std::cout << “Count: “ << count << std::endl;
count++;
}

return 0;
}

In this example, we showcase the usage of loops in C++. The `for` loop iterates five times, displaying the current iteration number. The `while` loop executes as long as the condition is true, printing the current count. Loops are powerful constructs that allow you to repeat a block of code until a certain condition is met.

### Example 5: Arrays

cpp

`#include <iostream>`

int main() {
int numbers = {1, 2, 3, 4, 5};

for (int i = 0; i < 5; i++) {
std::cout << “Number: “ << numbers[i] << std::endl;
}

return 0;
}

This example introduces arrays in C++. We declare an integer array named `numbers` and initialize it with five values. The `for` loop is then used to iterate through the array and display each element on the console. Arrays provide a convenient way to store and access multiple values in C++.

### Example 6: Functions

cpp

`#include <iostream>`

// Function to calculate the square of a number
int square(int num) {
return num * num;
}

int main() {
int number;
std::cout << “Enter a number: “;
std::cin >> number;

int result = square(number);
std::cout << “Square: “ << result << std::endl;

return 0;
}

In this example, we define a function `square` that calculates the square of a given number. The `main` function prompts the user to enter a number, calls the `square` function, and displays the squared result. Functions allow you to organize your code into reusable blocks, making your programs more modular and easier to maintain.
