C++

Modify the pizza slices program so it uses the parameterized constructor in the ModifyThis10 Square.h file. Test

.cpp file

//Pizza Slices.cpp //Displays the number of square slices //that can be cut from a square pizza //Created/revised by on

#include #include "ModifyThis10 Square.h" using namespace std;

int main() { //instantiate Square objects Square wholePizza; Square pizzaSlice; //declare variables double wholeSide = 0.0; double sliceSide = 0.0; double wholeArea = 0.0; double sliceArea = 0.0; double numSlices = 0.0; //get side measurements cout << "Whole pizza side measurement (inches): "; cin >> wholeSide; cout << "Pizza slice side measurement (inches): "; cin >> sliceSide; //assign side measurements to Square objects wholePizza.setSide(wholeSide); pizzaSlice.setSide(sliceSide);

//calculate areas wholeArea = wholePizza.calcArea(); sliceArea = pizzaSlice.calcArea();

//calculate number of slices if (sliceArea > 0.0) numSlices = wholeArea / sliceArea; //end if cout << "Number of slices: " << numSlices << endl; return 0; } //end of main function
