Question

Parents of the pupils of the Park Primary School must pay an amount for outfits for the annual play. All
pupils take part in the play, except the Grade 0 pupils. The amount that the parents have to pay is
calculated as follows:
• The cost of the outfits for Grade 1 and 2 pupils is R45
• The cost of the outfits for Grades 3 to 5 is R65
• Grade 6 and 7 pupils may play one or two roles. If they play a leadrole, they may only play one role.
The cost of the outfits  is R70 if they play one role. If this role is a leadrole, the cost is R100. If they play two
roles, the cost is R130
Use a switchstatement and write down ONLY the necessary C++ statements to calculate and display
the amount to be paid or display an appropriate error message if required.
Do NOT write a complete program. Use the following variables:
int grade;
int fee;
bool leadrole; // true if a child plays a leadrole
bool roles2; // true if a child plays 2 roles
Assume that values have been assigned to these variables already.

#include<iostream>
using namespace std;

int main()
{
   int grade ;
   int fee;
   bool leadrole ; // true if a child plays a leadrole
   bool roles2 ; // true if a child plays 2 roles
   switch (grade)
   {
       case 0:
           fee = 0;
           break;
       case 1:
