Question

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;

Explanation / Answer

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;

}

return 0;

}
