Question

USING C++ PROGRAM

Write a program to compute, and output to the screen, the number of cat treats that can be bought from a vending machine, along with amount of resulting change. Each treat costs 47¢ and purchases are made in whole-dollar increments, such as $1, $2, $3, $4, $5, ellipsis, that are input, via the keyboard, by the user. For example, if a person inserts $4, they will recieve 8 treats and 24¢ change. Your submission should include a screenshot of the execution of the program using each of the values $1, $7 and $29. Write a program to compute, and output to the screen, the value of the variable x of the polynomial x^2 + 2x = 1 = p, for some constant P greaterthanorequalto 0 that is input, via the keyboard, by the user. For example. If p = 9, then x = 2. Your submission should include a screenshot of the execution of the program using each of the values p = 0.14, 16, 151.93.

Explanation / Answer

#include <iostream>

using namespace std;

int main()
{
int money;
cout<<" W-E-L-C-O-M-E VENDING MACINE ";
cout<<" Each treat cost is 47 cent ";

cout << "Insert a Money : $";
cin>>money;

int treat,change;
treat=(money*100)/47;
change=(money*100)%47;

cout<<"You receive "<<treat <<" treats and change "<<change<<" cents ";
return 0;
}

------------------

output sample 1:-

W-E-L-C-O-M-E VENDING MACINE

Each treat cost is 47 cent
Insert a Money : $4
You receive 8 treats and change 24 cents

-----------------

output sample 2:-

W-E-L-C-O-M-E VENDING MACINE

Each treat cost is 47 cent
Insert a Money : $1
You receive 2 treats and change 6 cents

-----------

output sample 3:-

W-E-L-C-O-M-E VENDING MACINE

Each treat cost is 47 cent
Insert a Money : $7
You receive 14 treats and change 42 cents

----------------------

output sample 4:-

W-E-L-C-O-M-E VENDING MACINE

Each treat cost is 47 cent
Insert a Money : $29
You receive 61 treats and change 33 cents

------------------------------------------------------------------------------------------------------------------------------

Answer 2:-

#include <iostream>
#include <cmath>
using namespace std;

int main() {

float a,b,p, c, x1, x2, determinant;

cout << "Enter the value of P : ";
cin >>p;

a=1;
b=2;
c=(1-p);

determinant = b*b - 4*a*c;

x1 = (-b + sqrt(determinant)) / (2*a);

cout << "x = " << x1 << endl;

return 0;
}

-------------

output sample 1:-

Enter the value of P : 9
x = 2

----------

output sample 2:-

Enter the value of P : 0.14
x = -0.625834

---------------------------------

Enter the value of P : 16
x = 3

--------------

Enter the value of P : 151.93
x = 11.326

---------------------------------------------------------------------------------------------
