Strings

Strings are objects that represent sequences of characters. In C++, there are two ways to create strings: string class or using C-style character strings.

The standard string class provides support for strings in C++.

std::string welcome = "Hi";
std::string user_name = "@sonny";
std::string message = "Good nite! 😇";

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 null character '\0'.

char message[] = "Howdy";

So here’s the memory presentation:

Character |   'H'    'o'    'w'    'd'    'y'   '\0'
Index     |    0      1      2      3      4      5
Address   |  23451  23452  23453  23454  23455  23456
