C++ 17: String vs Char Array

What are the main differences between strings and char arrays in C++ 17?

In C++ 17, strings are objects of the std::string class, while char arrays are simple arrays of characters. Strings offer more functionality, like dynamic sizing and built-in methods for manipulation.

Can you give me an example of when to use a string instead of a char array?

Sure! Use std::string when you need to handle text that changes in size, like user input. Char arrays are better for fixed-size strings, like file paths.

Are there any performance differences between the two?

Yes, char arrays can be more efficient in terms of memory usage and speed for fixed-size data, but std::string provides better safety and ease of use.

What about memory management? How does it differ?

std::string manages memory automatically, while with char arrays, you need to handle memory allocation and deallocation manually, which can lead to errors.
