Strings are objects that represent sequences of characters. In C++, the two ways to create strings are with the
string class or with C-style character strings.
string class provides support for strings in C++.
std::string welcome = "Hi";std::string user_name = "@sonny";std::string message = "Good nite! 😇";
C-Style Character Strings
The C-style character string originated from the C language and continues to be supported within C++.
In C, the string is actually an array of characters, followed by a
char message = "Howdy";
So here’s the memory presentation:
Character | 'H' 'o' 'w' 'd' 'y' '\0'Index | 0 1 2 3 4 5Address | 23451 23452 23453 23454 23455 23456

- Returns a portion of a string specified by a starting position and length.
