Final Code:
#include <iostream>
#include <iomanip>
using namespace std;
const double PI = 3.14;
const double RATE = 0.25;
void findArea(float, float&);
void findCircumference(float, float&);
int main()
{
cout << fixed << showpoint << setprecision(2);
float radius = 12;
cout <<" Main function outer block" << endl;
cout <<" radius is active here" << endl << endl;
{
float area;
cout << "Main function first inner block" << endl;
cout << "area, radius are active here" << endl << endl;
findArea(radius);
cout << "The radius = " << radius << endl;
cout << "The area = " << area << endl << endl;
}
{
float radius = 10;
float circumference;
cout << "Main function second inner block" << endl;
cout << "circumference, radius are active here" << endl << endl;
findCircumference (radius);
cout << "The radius = " << radius << endl;
cout << "The circumference = " << circumference << endl << endl;
}
cout << "Main function after all the calls" << endl;
cout << " are active here" << endl << endl;
return 0;
}
void findArea(float rad, float& answer)
{
cout << "AREA FUNCTION" << endl << endl;
cout << "area, radius and PI are active here"<< endl << endl;
area = PI * radius^2 ;
// FILL in the code, given that parameter rad contains the radius, that
Return (area);
}
void findCircumference(float length, float& distance)
{
cout << "CIRCUMFERENCE FUNCTION" << endl << endl;
cout << "circumference,radius and PI are active here" << endl << endl;
circumference = 2 * PI * radius ;
return (circumference);
}
Output:
Area: 452.16
Circumference: 62.8
