Project 1: 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:
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;

| 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 |
Solution
Project 1: PI
// Calculating Pi for specified Iterations
// Using Leibinz’s Formula
#include <iostream>
#include<cmath>
#include<stdio.h>
using namespace std;
// Function to calculate Pi using Leibinz Formula
double cal_pi_leibniz(int iter)
{
int j=0;
double sum=0;
for(j=0; j<=iter; j++)
{
sum+= -1/(double)(2*j+1);
sum*=-1;
}
return sum;
}
int main()
{
int no_of_iteration;
cout << “Enter number of iterations to calculate: “;
cin >> no_of_iteration;
cout << \"The value of Pi after \" << no_of_iteration << \" iterations is approximately: \" << cal_pi_leibniz(no_of_iteration) * 4 << endl;
