what should i do if i would like to print the total price? also, if a customer orders more than 1 item,10% discount will be given,if more than 2 item,15% discount will be given. How do i do that?

[Konstantin2]

what should i do if i would like to print the total price?

AmountofSaleTotal = AmountofSale1 + AmountofSale2 + AmountofSale3 + AmountofSale4 + AmountofSale5 + AmountofSale6;

if a customer orders more than 1 item...

int cnt = 0;
cnt += num1 ? 1 : 0;
cnt += num2 ? 1 : 0;
cnt += num3 ? 1 : 0;
cnt += num4 ? 1 : 0;
cnt += num5 ? 1 : 0;
cnt += num6 ? 1 : 0;
float discnt = 0;
if (cnt > 2) discnt = 0.15;
else if (cnt > 1) discnt = 0.1;

Advice: using arrays.

int num[6] = {0, 0, 0, 0, 0, 0};
const double UnitPrice[6] = {5.50, 4.00, 7.50, 6.50, 7.00, 5.00};
