C++: std::string vs char array

What's the difference between std::string and char array in C++?

std::string is a class that manages strings with dynamic size, while a char array is a fixed-size array of characters.

Which one is better for memory management?

std::string is generally better for memory management as it automatically handles memory allocation and deallocation.

Can I use std::string for C-style string functions?

Yes, you can use std::string with C-style functions by converting it to a char array using the c_str() method.

Are there performance differences between the two?

Yes, std::string may have some overhead due to dynamic memory management, while char arrays can be faster for fixed-size strings.
