Question 3: How a program can use a function?

Answer:

The calling program just needs to write the function name and provide its arguments (without data types). It is important to note that while calling a function, we don't write the return value data type or the data types of arguments.

Question 4: How can we initialize data members of contained object at construction time?

Answer:

Initializer list is used to initialize the contained objects at the construction time.

Question 5: How is the following cout statement interpreted by compiler?
cout << a << b << c ;

Question 6: How learning to design programs is like learning to play soccer?

Answer:

"Learning to design programs is like learning to play soccer. A player must learn to trap a ball, to dribble with a ball, to pass, and to shoot a ball. Once the player knows those basic skills, the next goals are to learn to play a position, to play certain strategies, to choose among feasible strategies, and, on occasion, to create variations of a strategy because none fits.

Question 9: Briefly explain CMPS.

Answer:

CMPS subtracts the source location DS:SI from the destination location ES:DI. Source and Destination are unaffected. SI and DI are updated accordingly. CMPS compares two blocks of memory for equality or inequality of the block. It subtracts byte by byte or word by word. If used with a REPE or a REPNE prefix is repeats as long as the blocks are same or as long as they are different. For example it can be used for find a substring. A substring is a string that is contained in another string. For example "has" is contained in "Mary has a little lamp." Using CMPS we can do the operation of a complex loop in a single instruction. Only the REPE and REPNE prefixes are meaningful with this instruction
