Characters

1. Any single character:
   char letter;
   
   
2. Assignment:
   letter = 'X';
   cin >> letter;
   
   
3. Internal representation: ASCII table.
   
   
4. Conversion between int and char:
   int('A') = 65
   char(65) = 'A'
   
   
5. How would you convert from character '2' to the integer 2?
   
   
6. Escape sequences: \ causes the next character to be read literally.
   
   cout << "I said "no" and left"   //error!
   cout << "I said \"no\" and left" //fine
   
   The same:
      cout << "Hello" << endl;
      cout << "Hello\n";
   
   \n: newline
   \t: tab
   \a: bell
