Question

The main purpose of this lab is to reinforce the lectures on code style and documentation.

Make as many improvements to the code style as you can including white space, variable names, etc. (NOTE: do this manually – no automated formatting tools allowed). Comment the file completely.

#include <iostream>

#include <cmath>using namespace std;

const int A_CONSTANT = 3;

void functionA(int a[], int aNumber);

void functionB(int a[], int anotherNumber);

void functionC(const int anArray[], int aNumber);

void functionD(int& sum);

int functionE(double number); void functionF(int n);

int main( ){

int production[A_CONSTANT];

cout << "This program displays a graph showing\n" << "production for each factory in the company.\n";

functionA(production, A_CONSTANT);

functionB(production, A_CONSTANT);

functionC(production, A_CONSTANT);

return 0;}

void functionA(int a[], int aNumber){

for (int someNumber = 1;someNumber <= aNumber; someNumber++)

{ cout << endl << "Enter production data for plant number " << someNumber << endl; functionD(a[someNumber - 1]);}}

void functionD(int& sum){

cout << "Enter number of units produced by each department.\n" << "Append a negative number to the end of the list.\n";

sum = 0; int next;

cin >> next;

while (next >= 0) {

sum = sum + next;

cin >> next; }

cout << "Total = " << sum << endl;

  

}

void functionB(int a[], int anotherNumber){

for (int index = 0; index < anotherNumber; index++)

a[index] = functionE(a[index]/1000.0);

  

}

int functionE(double number) {

return static_cast<int>(floor(number + 0.5));

  

}

void functionC(const int anArray[], int aNumber){

cout << "\nUnits produced in thousands of units:\n";

for (int someNumber = 1; someNumber <= aNumber; someNumber++) {

cout << "Factory #" << someNumber << " ";

functionF(anArray[someNumber - 1]);

cout << endl;

}

}

void functionF(int n) {

for (int count = 1; count <= n; count++) cout << "*";

  

}

Answer 1

PascalCase: In pascal case starting letter of each word should be capitalized. It is easy for reading.

Example: LongFunctionName;

camelCase: It is same as PascalCase except the first letter should not be capitalized.

example: longFunctionName:

* We used camelCase for function names and varibale names

It is common in c++ to use camelCase for functions and varible names.

In our code everything looks good except the indentation. So i adjusted it.

#include <iostream>

#include <cmath>

using namespace std;

const int A_CONSTANT = 3;

void functionA(int a[], int aNumber);

void functionB(int a[], int anotherNumber);

void functionC(const int anArray[], int aNumber);

void functionD(int& sum);

int functionE(double number);

void functionF(int n);

int main( )
{
    int production[A_CONSTANT];
    cout << "This program displays a graph showing\n" << "production for each factory in the company.\n";
    functionA(production, A_CONSTANT);
    functionB(production, A_CONSTANT);
    functionC(production, A_CONSTANT);
    return 0;
  
}

void functionA(int a[], int aNumber){
    for (int someNumber = 1;someNumber <= aNumber; someNumber++)
    {
        cout << endl << "Enter production data for plant number " << someNumber << endl;
        functionD(a[someNumber - 1]);
      
    }
  
}

void functionD(int& sum){
    cout << "Enter number of units produced by each department.\n" << "Append a negative number to the end of the list.\n";
    sum = 0; int next;
    cin >> next;
    while (next >= 0)
    {
        sum = sum + next;
        cin >> next;
      
    }
    cout << "Total = " << sum << endl;
  
}

void functionB(int a[], int anotherNumber){
    for (int index = 0; index < anotherNumber; index++)
    a[index] = functionE(a[index]/1000.0);
  
}

int functionE(double number) {
    return static_cast<int>(floor(number + 0.5));
  
}

}
