Basic C++ Concepts

C++, being a statically typed, compiled language, is one of the powerful programming languages used in various real-world applications. Before delving into the advanced use cases of C++, let's revisit some of the fundamental concepts.

C++ allows for different programming styles, namely procedural (like C) and object-oriented programming (OOP). The OOP concept in C++ aids in developing scalable and complex modules with ease.

For the basics, a simple program in C++ can be written to display an output. Here is an example:

1#include <iostream>
2using namespace std;
3int main() {
4  // Simple output in C++
5  cout << "Hello from C++!";
6  return 0;
7}

In this short program:

• #include <iostream> is a preprocessor command that includes/imports the input-output stream package in the program.
• using namespace std; tells the compiler to use the standard namespace.
• int main() is the main function where the program execution begins.
• cout << "Hello from C++!"; displays the text on the console.

Understanding these fundamental concepts will lay a strong foundation as we proceed further to explore how C++ can be used in real-world applications like AI, Machine Learning, and Finance.
