Chapter 4, Problem 2PP
The area of an arbitrary triangle can be using the formula
where a, b, and c are the lengths of the sides, and s is the semiperimeter:
Write a void function that uses five parameters: three value parameters that provide the lengths of the edges and two reference parameters that compute the area and perimeter (not the semiperimeter). Make your function robust. Note that not all combinations of a, b, and c produce a triangle. Your function should produce correct results for legal data and reasonable results for illegal combinations.

XYZ store plans to give a festival discount to its customers. The store management has decided to give discount on the following criteria:
Shopping Amount
Discount Offered
>=500 and <1000
5%
>=1000 and <2000
8%
>=2000
10%
An additional discount of 5% is given to customers who are the members of the store. Create a program using user defined function that accepts the shopping amount as a parameter and calculates discount and net amount payable on the basis of the following conditions:Net Payable Amount = Total Shopping Amount – Discount.
The following formula can be used to determine the distance an object falls due to gravity in a specific time period:
d = 1⁄2 gt2The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the time in seconds that the object has been falling.
Write a function named fallingDistance that accepts an object’s falling time (in seconds) as an argument. The function should return the distance, in meters, that the object has fallen during that time interval. Write a program that demonstrates the function by calling it in a loop that passes the values 1 through 10 as arguments and displays the return value.

User needs to identify lower and upper values of each parameter. The identified range for the parameters should be then divided into 10 monotonic steps inside your program. Accordingly, you need to calculate the values and plot the shapes corresponding to all 10 values in the range identified by the user.
