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: https://stackoverflow.com/questions/43565043/visual-studio-2017-c-issue-with-string

Isn't it self describing? It brings the string datatype to the program.

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