Introduction to C++

C++ is a powerful, high-performance programming language that extends the C language with object-oriented and generic programming features. It is widely used for system-level programming, game development, and performance-intensive applications. C++ allows fine-grained control over system resources while offering advanced features for scalability and efficiency.

What is C++ Best Used For?

• Developing operating systems, compilers, and embedded systems.
• Building high-performance applications like game engines and simulations.
• Creating software that requires real-time processing, such as robotics or telecommunications.
• Designing scalable systems with complex object-oriented structures.

Example C++ Program

This program demonstrates variables, a loop, and output.

#include <iostream>
#include <string>

int main() {
    // Declare variables
    std::string greeting = "Hello, C++ Programmer!";
    int count = 5;

    // Display greeting
    std::cout << greeting << std::endl;

    // Loop through numbers 1 to count
    for (int i = 1; i <= count; i++) {
        std::cout << "Iteration: " << i << std::endl;
    }

    // Print completion message
    std::cout << "Loop completed! Total iterations: " << count << std::endl;

    return 0;
}

Explanation:

1. Variables: greeting is a string holding the welcome message, and count is an integer for the loop limit.
2. Loop: The for loop iterates from 1 to count, printing each iteration with the std::cout stream.
3. Output: The program outputs the greeting, each iteration, and a completion message.

Sample Output:

Hello, C++ Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
