C++ Program to Demonstrate the use of String Class

This C++ Program which demonstrates the use of string class. The program uses a special header for using string class. A ‘string’ object is created, the name of the user is taken as input to save it into the string object, the length of string object is printed and also the string object is printed by going through the object by use of iterators.

Here is source code of the C++ program which demonstrates the use of string class. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

  11.     std::string s;
  12.     cout << "Enter your first name : ";
  13.     cin >> s;
  14.     cout << "The length of your name is " << s.length() << endl;
  15.     cout << "Nice to meet you ";
  17.     /* Printing using const_iterator */
  18.     for (std::string::const_iterator i = s.begin(); i != s.end(); i++)
  19.         cout << *i;
  20.     cout << "!" << endl;
  21. }

$ g++ main.cpp
$ ./a.out
Enter your first name : George
The length of your name is 6
