SECTION B 80 MARKS QUESTION 1 12 marks 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 I 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: ant grade: bool Leadrole: 1 true if a child plays a leadrole bool roles 2: 1 true if a child plays 2 roles Assume that values have been assigned to these variables already.

Answer 1

int grade;
int fee;bool leadrole; //true if a child plays a lead role
bool roles2; //true if a child plays 2 roles

//switch statement
switch(grade)
{
//grade 0 pupils
case 0:
fee = 0; break;
//grade 1 and 2 pupils
case 1: case 2:
fee = 45; break;
//grade 3 to 5 pupils
case 3: case 4: case 5:
fee = 65; break;
//grade 6 and 7 pupils
case 6: case 7:
if(leadrole) fee = 100;
else if(roles2) fee = 130;
else fee = 70;
break;
default: cout<<"Invalid grade! "<<endl;
}

//display the fee
cout<<"Fee = " << fee <<endl;
