3. Describe the basic structure of a C++ program with all necessary blocks. (07 MARKS)

Q2

1. When can you make function inline? What are the advantages of making function inline? (03 MARKS)
2. Following is a main() program. (04 MARKS)

   
   void main()
   --- Content provided by FirstRanker.com ---
   { time T1; int duration = 85; T1 = duration;
   } 

   Where time is a class which contains variables hrs and minutes. duration stores total time in minutes. Define a class time with necessary functions to break-up the duration in maximum hours and remaining minutes and store them into hrs and minutes respectively.

1. Consider following class declarations. (04 MARKS)

   
   class ABC;
   --- Content provided by FirstRanker.com ---
   class XYZ{ int X;
   public: void get_x(int i) {x=i;} friend void sum(XYZ,ABC);
   }; class ABC{ int y;
   public: void get_y(int i) {y=i;} friend void sum(XYZ,ABC);
   }; 

   By considering above class declarations, define a function sum() at outside the class to find out the sum of x and y and display the result. Also define the main() which satisfy above class declarations.
