1. Rewrite the following multiway if statement as a switch statement: if (a == 1) sum = sum + 2.5; else if (a == 2) sum = sum + 5.0; else if (a == 3) sum = sum + 7.5; else if (a == 4) sum = sum +...

1. Rewrite the following multiway if statement as a switch statement:

if (a == 1)

sum = sum + 2.5;

else if (a == 2)

sum = sum + 5.0;

else if (a == 3)

sum = sum + 7.5;

else if (a == 4)

sum = sum + 10.0;

2. What value is assigned to discount by the following code?

double discount;

char code = 'B';

switch (code)

{

case 'A':

discount = 0.0;

case 'B':

discount = 0.1;

case 'C':

discount = 0.2;

default:

discount = 0.3;

} // end switch
