Consider a software system that computes income tax based on adjusted gross income (AGI) and number of dependents according to following rules If AGI is between 25000 and 50000 and number of dependents less than 3 tax due is 22% of AGI otherwise, tax rate is 20%
If AGI is between 50001 and 100000 and number of dependents less than 3 tax due is 27% of AGI otherwise tax rate is 25%
If AGI is between 100001 and 1 million and number of dependents less than 3 tax is 36 % of AGI, otherwise tax rate is 33%
This software does not calculate tax for people over 1 million and tax will not be deducted for families with AGI less than 25000. Suppose you need to test this application using equivalent partitions.
a) Identify equivalent classes for income and number of dependents
b) Develop test cases for weak normal equivalent partition testing?
c) Draw a graph that shows strong normal and strong robust test cases (like the one discussed during the lecture).
d) How many test cases are needed if you were to use strong normal?
e) How many test cases are needed if you were to use strong robust

In this lab, you add a loop and the statements that make up the loop body to a c++ program that is provided. when completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. your loop should execute until the user enters the character x instead of l for left-handed or r for right-handed. the inputs for this program are as follows: r, r, r, l, l, l, r, l, r, r, l, x variables have been declared for you, and the input and output statements have been written.

Look at the far left lane in the picture. explain what the red car is doing and what it needs to do to travel safely.

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
