What is <string> actually for?

Question

I have no Idea what does Text says on my lessons and I have no Idea what is it used for?
Maybe someone can give me an Understandable explanation or Demonstrate the Usage of <string> ?
Thanks.

Answer 1

We know that int can be used to store integers like 39, 42, 1, etc. In the same fashion, char is used to store characters like 'a', 'b', '£', etc.

int n = 39;
char c = 'a';

Strings are a collection of characters in a sequence. For example, "hello", "this is a sentence", "welcome", etc. Similar to how you would store integers in integer variables and characters in character variables, you can store strings, in string variables.

#include <iostream>
#include <string>

int main() {
std::string str = "Hello!";
std::cout << str;
}

Seb TheS From what I've read, the standard does not dictate that <iostream> should include <string>, it's mostly just the compiler (or IDEs) making things easier for us. Consider:

Answer 5

string library is already includes with iostream, so you do not need to separately include string library, if you already included iostream library.
