Using C++ Download the file.Comment the file completely. You should submit your updated source file through the lab drop box in Blackboard. I need help with re-naming the variables and making the code look better. (Stick to giving the variables better names and to stick to the documentation style for c++) *************************************** CODE: #include #include 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 " << "production for each factory in the company. "; 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. " << "Append a negative number to the end of the list. "; 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(floor(number + 0.5)); } void functionC(const int anArray[], int aNumber) { cout << " Units produced in thousands of units: "; 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 << "*"; }
