Question

Hi, I need to solve this question using C++ programming language. Thank you.

Note: I have included Program - 5-23, General Program Format Rules, if you needed.

 

Program 5-23

// This program tests for file open errors.

#include <iostream>

#include <fstream>

using namespace std;

 

int main()

{

ifstream inputFile;

int number;

 

// Open the file.

inputFile.open("BadListOfNumbers.txt");

 

// If the file successfully opened, process it.

if (inputFile)

{

// Read the numbers from the file and

// display them.

while (inputFile >> number)

{

     cout << number << endl;

}

 

// Close the file.

inputFile.close();

}

else

{

// Display an error message.

cout << "Error opening the file.\n";

}

return 0;

}

General Program Format Rules Each program should have 1. A heading comment at the top of the program that contains information in this form: /* Programmer I. Will Ritem : Date due : July 12, 2020 Description : This program will calculate the average of three integers from the user */ A comment above each function (other than main) in this form: / * : getAverage : 3 integers : This function will calculate the average of its three integer parameters : the average (a double) Function Receives Description Returns Preconditions : none * / Note: preconditions are what the function is assuming to be true in order to do its job. For instance, a function that calculates the square root of its parameter can be written one of two ways: With no preconditions, which means the function itself must check to see if its parameter is not a negative number, OR а. b. Have a precondition that the parameter is non-negative, in which case it's the caller's responsibility to make sure the parameter is non-negative before calling the function. A precondition is like a contract in which the function says "Ill do this, but first you're promising my precondition is met." 3. Variables and constants with descriptive names "average" instead of "ave", and so on. – so, "radius" instead of "rad", "area" instead of "ar", Please don't use global variables unless a program says it's OK. If you don't know what a global variable is, please learn about them in section 6.10 in the text. Using global constants, on the other hand, is fine (also in section 6.10). 4. The order that parts of your program should follow is like this: Heading comment (#1 above) b. а. #includes section using namespace std; d. C. global constants (Note: this doesn't say global variables, which aren't allowed) typedefs and struct declarations f. е. g. h. function prototypes the main () function other functions, each with its own comment (#2 above) 6. Please don't "hardcode" array boundaries when using loops, functions, etc. Instead, declare a global constant (see 5d above) like this: const int ARRAY SIZE = 25; then write the loop like this: for (int x = 0; x < ARRAY SIZE; x++) and not like this: for (int x = 0; x <(25/; x++) 2. 5.
