Answered Essay: Exercise 1: Fill in the following chart by listing the identifiers (function names, variables, constants) GLOBALMain Ma

I need to complete EACH ONE OF THESE 5 EXERCISES with a given code. Every instruction is included in the pictures.Exercise 1: Fill in the following chart by listing the identifiers (function names, variables, constants) GLOBALMain Main Main Area Circum- (inner 1)(inner 2) Exercise 2: For each cout instruction that reads: cout << LIST THE IDENTIFIERS THAT are active here << endl: Replace the words in all caps by a list of all identifiers active at that location. Change it to have the following form: cout<< area, radius and PI are active here << endl; Exercise 3: For each comment in bold, place the proper code to do what it says. NOTE: area ,2 circumference 2T.


The code I need to modify with the exercises:

#include <iostream>

#include <iomanip>

using namespace std;

// This program will demonstrate the scope rules.

// PLACE YOUR NAME HERE

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 <<” LIST THE IDENTIFIERS THAT are active here” << endl << endl;

{

float area;

cout << “Main function first inner block” << endl;

cout << “LIST THE IDENTIFIERS THAT are active here” << endl << endl;

 

// Fill in the code to call findArea here

 

cout << “The radius = ” << radius << endl;

cout << “The area = ” << area << endl << endl;

}

{

float radius = 10;

float circumference;

 

cout << “Main function second inner block” << endl;

cout << “LIST THE IDENTIFIERS THAT are active here” << endl << endl;

 

// Fill in the code to call findCircumference here

 

cout << “The radius = ” << radius << endl;

cout << “The circumference = ” << circumference << endl << endl;

 

}

 

cout << “Main function after all the calls” << endl;

cout << “LIST THE IDENTIFIERS THAT are active here” << endl << endl;

 

return 0;

}
