C++ Introduction to strings

A string is a collection of characters kept in a single unit of memory in C++. The standard library’s string class serves as its representation. Numerous built-in functions for manipulating strings are available in the string class, including concatenation, comparison, locating substrings, and others.

The string header file must be included in order to use strings in C++.

#include <string>

To declare a string variable, you can use the string class like this:

string str;

You can also initialize a string with a value like this:

string str = "Hello, world!";

Overall, strings are an essential and powerful data type in C++ for working with text and character data.
