Assignment 2 Question 4

Hi there,

Anybody that is busy with or done with assignment 2, Question 4...
I am a bit confused about question 4b where you must calculate the actual amount spent per child. Can this be done with a nested if statement or is there an better way of doing this.
How do you actually get the actualAmountSpent?

Here is part of my code:
#include <iostream>
using namespace std;

const float maxPerUnit = 20000.00;
//minPerChild includes a standard gift consisting of a bath towel and a facecloth
const float minPerChild = 100.00;
const float maxPerChild = 180.00;
//depending on the amount, the child may also get one or more of the following:
const float TOOTHBRUSH = 29.95;
const float HIGHLIGHTERS = 25.95;
const float CRAYONS = 17.95;
const float NOTEBOOK = 12.95;
const float PEN = 9.99;

float calcAllowedPerChild(int nrChildrenP)
{
return((maxPerUnit / nrChildrenP));
}

float calcActualAmount(float amtGiftP, int nrChildrenP)
{
... .... ... ... ... ... ... ... .. .. .... .... ....
}

int main()
{
float amtGift; //Allowed amount per child
float amtSpentPerChild = 0.00; //Actual amount spent per child
float totalSpent = 0.00; //Total spent for one orphanage
float totalAll = 0.00; //Total spent for all 4 orphanages
int nrChildren; //Number of children per orphanage

cout << "Enter the number of children: " << endl;
cin >> nrChildren;
amtGift = calcAllowedPerChild(nrChildren);
cout.setf(ios::fixed);
cout.precision(2);
cout << endl << "Allowable amount per child : R" << amtGift;
cout << endl << endl;
amtSpentPerChild = calcActualAmount(amtGift, nrChildren);
cout << endl << "Actual amount spent per child : R";
cout << amtSpentPerChild << endl << endl;

return 0;

That will depend on the rules for deciding what a child gets from the extras and how you decide which ones to allocate given your funding available.

If your rule is that, given the amount of money extra per child, allocate the most expensive item and see how much is left over, allocate the next most expensive item and so on until the extra funds are exhausted. If that is the case, you'll use sequencial if statements

Language: C++
float outstanding = ...;
if (outstanding >= TOOTHBRUSH){
   // allocate toothbrush funds
   outstanding -= TOOTHBRUSH;
}
if (outstanding >= HIGHLIGHTERS){
   // allocate highlighters
   outstanding -= HIGHLIGHTERS;
}
/// and so on ...

I hope this helps.
