other two and display the value of the new point.

Create the equivalent of a four function calculator. The program should request the userto enter a number, an operator and another number. It should then carry out the specified

arithmetical operation adding, subtracting, multiplicating or dividing the number finally.It should display the result. When it finishes the calculation, the program should ask of

the user wants to do another calculation

store these 3 parts separately. Call the structure variable and type phone int and haveinput a number for the other one there. Display both numbers.

Create two classes DM and DB which store the value of distance. DM stores distances inmeters and centimeters and DB in feet and inches. Write a program that can read values

for the class objects and add one object of DM with another object of DB. Use a friendfunction to carry out the addition operation. The object that stores the results may be a

DM object or DB object, depending on the units in which the results are required. The

display should be in the format of feet and inches or meters and centimeters depending onthe object on display.

Imagine a tollbooth with a class called tollbooth. The two data items are a type unsignedint to hold the total number of cars and a type double to hold the total amount of money

collected. A constructor initializes both these to 0. A member function callednopayCar() increments the car total but adds nothing to the cash total. Finally a member

function called display(), displays to the two totals. Include a program to test this class.

This program should allow the user to push one key to count a paying car and another tocount a nonpaying car. Pushing the Esc Key should cause the program to print out thetotal cars and total ash and then exit.

#include #include

Raising a number n to a power p is the same as multiplying n by itself p times. Write aprogram, function called power() that takes a double value. Use a default argument of 2

for p, so that if this argument is omitted, the number will be squared. Write a main()function that gets values from the user to test the function.

#include #include

Write a function called reverseit() that reverses a string (an array of characters). Use afor loop that swaps the first and last characters, then second and next to last characters

and so on. The string should be passed to reverseit() as an argument.

Write a program to exercise reverseit(). The program should get a string from the user,

call reverseit(), and print out the results. Use an input method that allows embeddedblanks. Test the program with Napoleons famos phase, Able was I ere I Elba

Create some objects of the string class and put them in Deque, some at the head of theDeque and some at the tail. Display the contents of the Deque using the forEach()

function and a user written display function. Then search the Deque for a particularstring using the first That() function and display any string that match. Finally remove all

the items from the Deque using the getLeft() function and display each item. Notice the

order in which the items are displayed using getLeft(), those interested on the left (head)of the Deque are removed in first in first out order. The opposite would be true ifgetRight() were used.

A hospital wants to create a database regarding its indoor patients. The information to

class to store the above information. The member function should include function toenter information and display a list of all the patients in the database. Create a derived

class to store the age of the patients. List the information about all the patients to storethe age of the patients. List the information about all the pediatric patients (less than 12
