Project 1: Pi

Write a C++ program that approximates the value of using the Gregory-Leibniz formula:

Since this formula is an infinite series, you will need to prompt the user for the number of iterations (summation terms) they want to use in the calculation. For example, if the user indicates "4" iterations, the result would be = 4 - 4/3 + 4/5 - 4/7 or approximately 2.89524. If the user indicates "10" iterations, the result would be = 4 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 + 4/13 - 4/15 + 4/17 - 4/19 or approximately 3.04184. If the user indicated "10000" iterations, the result would be approximately 3.14149. Thus, as the number of summation terms increases, the result converges on true value of PI.

Rather than putting all your code in main(), use functions to perform the calculation. Embed your program in a loop so that the calculation can be repeated multiple times.

Project 2: Tailor

The purpose of this C++ program is to determine how much cloth in square inches is needed to make a certain type of garment. You should base your calculations on the following table:

Pants	Shirts	Shorts
2 1/2 square inch per waist size inch of the person being fitted	2 3/8 square inch per waist size inch of the person being fitted	1 3/10 square inch per waist size inch of the person being fitted
1/2 square inch per height inch of the person being fitted	4/9 square inch per height inch of the person being fitted	1/4 square inch per height inch of the person being fitted
1/10 square inch per waist size inch of the person being fitted, if pleaded front is desired	2 4/5 square inch per arms length inch of the person being fitted, if long sleeves are desired	If pockets are desired, add an extra 15% to the fabric amount calculated so far
If baggy look is desired, add an extra 10% to the fabric amount calculated so far

Rather than putting all your code in main(), use functions to perform the calculation. Embed your program in a loop so that the calculation can be repeated multiple times. Use constants to hold the literal values in the above table, for example:

const double PANTS_WAIST_FACTOR = 2 + 1.0/2;
