6. Standard Output Stream

• 
      typename      object name
      ------------  -----------
      std::ostream  std::cout;  // cout is a predefined object
  
  

• Usage example:

  
      #include <iostream> // C++ standard library header
  
      using std::cout;    // cout declared inside std namespace
  
      int main()
      {
          int x = 65;
          cout << x;      // display value of number 65
          cout.put( x );  // display character 'A'
          return 0;
      }
  
      /* This program prints:
      65A
      */
