C++11: std::string vs C-string

What are the main differences between std::string and C-strings in C++?

The main differences include memory management, ease of use, and safety. std::string handles memory automatically, while C-strings require manual management.

Can you explain how memory management works for both?

Sure! std::string allocates memory dynamically and manages it automatically, while C-strings are just arrays of characters that require you to allocate and deallocate memory manually.

Which one is safer to use?

std::string is generally safer because it prevents buffer overflows and manages memory automatically, reducing the risk of memory leaks.

Are there performance differences between them?

Yes, std::string may have some overhead due to dynamic memory management, but it often provides better performance for string manipulation due to its built-in functions.

When should I use std::string over C-strings?

You should use std::string when you need ease of use, safety, and functionality. C-strings are suitable for low-level programming or when interfacing with C libraries.
