C++ Strings vs Char Arrays

What are the main differences between strings and char arrays in C++?

In C++, strings are objects of the std::string class, while char arrays are simple arrays of characters. Strings manage memory automatically and provide many useful functions, whereas char arrays require manual memory management and lack built-in methods.

Which one is better to use in modern C++?

Generally, std::string is preferred in modern C++ due to its ease of use, safety, and built-in functionality. Char arrays can be useful in specific scenarios, like low-level programming or when performance is critical.

Can you give an example of how to declare and initialize both?

Sure! For a char array, you can declare it like this: char myArray[] = "Hello";. For a string, you would do: std::string myString = "Hello";.

What about memory management for both?

Char arrays require you to manage memory manually, using new and delete if dynamically allocated. Strings handle memory automatically, resizing as needed, which reduces the risk of memory leaks.
