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.

   {
       //grade 1 and 2
       case 1 : fee=45;
               break;
       case 2: fee=45;
               break;
       //grade 3 to 5

       case 6:
       {
               //if two roles

           else if(roles2==false)
               fee=70;
      
       }
       break;
      
           case 7:
       {

       }
       break;
       //erro message
       default : cout<<"NOT A VALID GRADE\n";
      
   }

   cout<<"FEE IS: "<<fee<<endl;
   return 0;
}
