C++ is a powerful programming language widely used for developing software applications, system software, and game development. It offers a wide range of functionalities and features that make it a popular choice among developers.

In this article, we will provide you with some useful C++ code snippets and examples to demonstrate various concepts and techniques. Let’s dive in!

1. Hello World

Let’s start with a classic “Hello World” program in C++. This program simply prints the message “Hello, World!” to the console.

#include <iostream>

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

This code snippet demonstrates the basic structure of a C++ program, including the main() function, the standard input/output library (iostream), and the usage of the cout object to display output.

2. Variables and Data Types

C++ provides various data types to store different kinds of values. Here’s an example that shows how to declare and initialize variables of different data types:

#include <iostream>

int main() {
    int a = 5;
    float b = 3.14;
    char c = 'A';
    bool d = true;

    std::cout << "Value of a: " << a << std::endl;
    std::cout << "Value of b: " << b << std::endl;
    std::cout << "Value of c: " << c << std::endl;
    std::cout << "Value of d: " << d << std::endl;

    return 0;
}

This code snippet demonstrates the declaration and initialization of variables of types int, float, char, and bool. It also shows how to display these values using the cout object.

3. Conditional Statements

C++ provides conditional statements like if, else if, and else that allow you to control the flow of execution based on certain conditions. Here’s an example that demonstrates the usage of conditional statements:

#include <iostream>

int main() {
    int num = 10;

    if (num > 0) {
        std::cout << "Number is positive." << std::endl;
    }
    else if (num < 0) {
        std::cout << "Number is negative." << std::endl;
    }
    else {
        std::cout << "Number is zero." << std::endl;
    }

    return 0;
}

This code snippet checks the value of the num variable and prints a corresponding message based on whether the number is positive, negative, or zero.
