   Consider the following declarations:

   string greet = "Hello!";
   string welcome = "Welcome to computer science";
   string com = "to";

   What is the output of each of these subsequent code fragments?

   1. cout << greet.size() << endl;

   2. cout << welcome.size() << endl;

   3. cout << (com+com) << endl;

   4. cout << welcome.substr(8,5) << endl;

   5. cout << welcome.substr(5,8) << endl;

   6. cout << welcome.find("e") << endl;

   7. cout << welcome.find("e",10) << endl;

   8. cout << welcome.find("com") << endl;

   9. cout << welcome.find("com",5) << endl;

   10. cout << welcome.find(com) << endl;
