WRITE A C PROGRAM TO IMPLEMENT THE FOLLOWING The following f

***********WRITE A C++ PROGRAM TO IMPLEMENT THE FOLLOWING***********

The following function accepts objects by reference and indicates the result of the operation by storing a value in the variable pointed to by result. Implement the function using the classes defined in Question 1.

/**

* Determines the larger area between two Shape objects

* The larger area is stored in result

*/

void largerArea(Shape &a, Shape &b, double *result);

Your implementation belongs in a larger program, which produces the following output:

This Triangle has a perimeter of: 12 and an area of: 6

This Circle has a perimeter of: 12.5664 and an area of: 12.5664

The larger area is: 12.5664

This Triangle has a perimeter of: 24 and an area of: 24

This Circle has a perimeter of: 12.5664 and an area of: 12.5664

The larger area is: 24

Note, largerArea() must not produce terminal output, the value must be passed to the caller through the result pointer variable.

********I HAVE ALREADY STARTED THE PROGRAM(BELOW) AND JUST NEED HELP FINISHING IT**********

#include <iostream>

using namespace std;

void describeShape

int main()

{

triangle t;

circle c;

c.setDims(4);

t.setDims(3,4,5);

describeShape(t);

describeShape(c);

return 0;

}

Solution

#include <iostream>
#include <math.h>
using namespace std;
#define PI 3.14
//Class circle
class circle
{
public:
float radius;
//Sets the radius
void setDims(float r)
{
radius = r;
}
//Area pi*r*r
//perimeter 2 pi r
};

//Class Triangle
class triangle
{
public:
float aT, bT, cT, sT;
//Sets the side of the triangle
void setDims(int f,int s,int t)
{
aT = f; bT = s; cT = t;
}
//Area 1/2 *b *h
//perimeter Scalene Triangle a+b+c
};

//Class Shape
class Shape
{
public:
float areaC, periC;
float areaT, periT;
//Takes triangle class object and calculates the area and perimeter
void describeShape(triangle &t)
{
t.sT = (t.aT + t.bT + t.cT)/2;
t.sT = (t.sT * (t.sT - t.aT) * (t.sT - t.bT) * (t.sT - t.cT));
areaT = sqrt(t.sT);
periT = (t.aT + t.aT + t.cT);
}

//Takes circle class object and calculates the area and perimeter
void describeShape(circle &c)
{
areaC = PI * c.radius * c.radius;
periC = 2 * PI * c.radius;
}

//Find out the biggest area
void largerArea(Shape &a, Shape &b, double *result)
{
if(b.areaC > a.areaT)
*result = b.areaC;
else
*result = a.areaT;
}
};

int main()
{
double res;
triangle t;
circle c;
Shape s1, s2;
c.setDims(4);
t.setDims(3,4,5);
s1.describeShape(t);
s2.describeShape(c);
s1.largerArea(s1, s2, &res);
cout<<\"\ This Triangle has a perimeter of: \"<<s1.periT<<\" and an area of: \"<<s1.areaT;
cout<<\"\ This Circle has a perimeter of: \"<<s2.periC<<\" and an area of: \"<<s2.areaC;
cout<<\"\ The larger area is: \"<<res;
return 0;
}

Output:

This Triangle has a perimeter of: 11 and an area of: 6
This Circle has a perimeter of: 25.12 and an area of: 50.24
The larger area is: 50.24

If c.setDims(2);     t.setDims(8,9,5);

Output:

This Triangle has a perimeter of: 21 and an area of: 19.8997
This Circle has a perimeter of: 12.56 and an area of: 12.56
The larger area is: 19.8997
