Introduction to string and functions:

C++ Standard template library includes a header file called “string”.

The string header file provides us a data type called “string” with a variety of functions to make our life easier.

Syntax:

string <string_name>;\n

We can access each element of the string just like we access our character array strings(str[index]).

But they offer us a lot of advantages over the traditional character arrays, for instance, the string length function which is implemented in the given code.

Algorithm:

First, we will input a string from the user(whose length is to be found) and store it in a string variable s.
Then we will print the length of the string using the length function(s.length()).

Code:

#include <iostream>\n#include <string>  //for using string data type\n#include <cstdio>  //for using getline function to input string\nusing namespace std;\n\nint main(){\n\tstring s;\n\tcout << \"Enter a string\\n\";\n\tgetline(cin, s);  //taking input in the string\n\tcout << \"Length of the given string=\" << s.length();\n}\n

Output

Enter a string\nHello World\nLength of the given string=11\n\n
