Question

Chapter 21, Problem 21.15E

a.

Program Plan Intro

Program Plan:

Declare variable xCoordinate and yCoordinate of type int as private member of class.

Provide declaration of ostream and istream operator as friend function.

Program Description: To create point class having two integer data membersxcoordinate and ycoordinate and provide declaration for stream insertion and stream extraction overloaded operator functions.

b.

Program Plan Intro

Program Plan:

Define overloaded insertion operator <<. Inside the definition use an if-else statement to check if the failbit was set or not.

If not then display the value of xCoordinate and yCoordinate data members of point class else display the message that wrong input was entered.

Also inside the else part use call clear function of clear the failbit.

Define overloaded extraction operator>>. Inside the definition use ignore function to ignore the first bracket, then read the first interger value , then again use ignore to ignore the comma and extra space, next read the ycoordinatevalue and finally use ignore to skip the last closing bracket.

Program Description: To implement the overloaded insertion and extraction functions of class point in file point.cpp.

c.

Program Plan Intro

Program Plan:

Include header file point.h

Declare a variable A of type Point.

Use cin statement to read the value of point in variable A.

Use cout statement to display the value of variable A if correct value was entered.

Program Description: To write a driver program to test the Point class.

Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid."
