Question

The program has errors. Identify and make the necessary changes to make the program work. Remember to follow the rules of functions and arrays. Here is the expected output

Total = 20

Average = 15

Area = 150

Area = 70

Enter a value: 10

Value 1 entered = 10

Enter an integer: 20

Value 2 entered = 20

Enter an integer: 30

Value 3 entered = 30

..................................................................

#include <iostream>

using namespace std;

void total(int, int, int);

double average(int [], int);

void area(int = 30, int); void getValue(int&);

int getValue();

double getValue();

int main() { const int vSize = 5;

int numbers[vSize] = {9, 20, 12, 34, 0};

int num = 18;

double num2 = 1.2;

cout << "\nTotal = " << total(6, 10, 4);

cout << "\nAverage = " << average(numbers, vSize); cout << "\nArea = " << area();

cout << "\nArea = " << area(10, 7);

getValue(num);

cout << "Value 1 entered = " << num;

num = getValue();

cout << "Value 2 entered = " << num;

num2 = getValue(3.14);

cout << "Value 3 entered = " << num2;

return 0; }

int total(int val1, int val2, int val3){ return val1 + val2 + val3;

}

double average(int vList[], int vSize)

{ double average = 0; int sum = 0 for(int i = 0;

i < vSize; i++){ sum = sum + vList[i];

}

average = static_cast(sum) / vSize;

return average;

}

void area(int length = 30, int width){ return length * width;

}

void getValue(int value&){ cout << "Enter a value: ";

cin >> value&;

}

int getValue()

{

int inputVal;

cout << "Enter an integer: ";

cin >> inputVal;

return inputVal;

}

double getValue(){ double inputVal;

cout << "Enter an integer: ";

cin >> inputVal;

return inputVal;

}

Answer 1

I corrected the errors and got the required output

#include<iostream>

using namespace std;

int total(int, int, int);

double average(int [], int);

int area(int,int = 30);

void getValue(int&);

int getValue();

int main()

{

const int vSize = 5;

int numbers[vSize] = {9, 20, 12, 34, 0};

int num = 18,num2;

cout << "\nTotal = " << total(6, 10, 4);

cout << "\nAverage = " << average(numbers, vSize);

cout << "\nArea = " << area(vSize);

cout << "\nArea = " << area(10, 7);

getValue(num);

cout << "Value 1 entered = " << num;

num = getValue();

cout << "Value 2 entered = " << num;

num2 = getValue();

cout << "Value 3 entered = " << num2;

return 0;

}

int total(int val1, int val2, int val3)

{

return val1 + val2 + val3;

}

double average(int vList[], int vSize)

{

double average = 0;

int sum = 0;

for(int i = 0; i < vSize; i++)

{

sum = sum + vList[i];

}

average = static_cast<double>(sum) / vSize;

return average;

}

int area(int length,int width)

{

return length * width;

}

void getValue(int& value)

{

cout << "Enter a value: ";

cin >> value;

}

int getValue()

{

int inputVal;

cout << "Enter an integer: ";

cin >> inputVal;

return inputVal;

}

Output
