Write the definition for a class called Distance that has data member feet as integer and inches as float. The class has the following member functions:

                       void set(int, float) to give value to object

                       void disp() to display distance in feet and inches

                       Distance add(Distance) to sum two distances & return distance

                       1. Write the definitions for each of the above member functions.

                       2. Write main function to create three Distance objects. Set the value in two objects and call add() to calculate sum and assign it in third object. Display all distances.

(Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several trips by recording miles driven and gallons used for each trip. Develop a C++ program that uses a while statement to input the miles driven and gallons used for each trip. The program should calculate and display the miles per gallon obtained for each trip and print the combined miles per gallon obtained for all tankfuls up to this point.

Q1: (Salary Calculator) Develop a C++ program that uses a while statement to determine the gross pay for each of several employees. The company pays “straight time” for the first 40 hours worked by each employee and pays “time-and-a-half” for all hours worked in excess of 40 hours. You are givenalist of the employees of the company, the number of hours each employee worked last week and the hourly rate of each employee. Your program should input this information for each employee and should determine and display the employee’s gross pay.

Enter hours worked (-1 to end): 39

Enter hourly rate of the employee ($00.00): 10.00

Salary is $390.00 Enter hours worked (-1 to end): 40

Enter hourly rate of the employee ($00.00): 10.00

Salary is $400.00

Write a C++ program that converts a decimal number to a binary, octal, and

hexadecimal equivalents. First, the program will ask to fix a range for the lower and

upper limit in which the conversion is required. The lower limit should not be less than

0 and greater than the upper limit. For example, if you enter a negative number or

greater than the upper limit, then the program should print a message for the invalid

input and will ask you again to enter a decimal number within the range. If you

correctly specify the upper and lower limits, then the program will print a table of the

binary, octal and hexadecimal equivalents of the decimal numbers in the range of

lower limit through upper limit.

Specific grading criteria: In this program you should use all the loops (e.g., while,

do-while and for loop) each of them only one time. The output mentioned below is just

an example; more clear and well- presented output will improve your points.

Note: without using the functions. only do in main function and by using loops.

A number is called a happy number, if you start with the given number

and arrive at 1 by repeating the following process (as illustrated in the below example): (a)

compute the sum of the squares of given number digits (b) if the resultant value is 1, then

the number is happy number, else execute point (a) for the newly produced number.

Note that if a number is not a happy number, there will be an endless loop to this execution.

Goal: In this question, you are required to write C++ code that checks whether the number

entered by the user is a happy number or not for 10 cycles/iterations only.

Example: Assume a number 19

Define a function CoordTransform() that transforms the function's first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10. 

Using the CelsiusToKelvin function as a guide, create a new function, changing the name to KelvinToCelsius, and modifying the function accordingly.
