Exercise: Calculate a Shop Total

Total after the discount

A market stall needs the final price after a discount. The starter already has stdio.h and main; work in the marked area. Multiply price by quantity before subtracting the discount. Run the program to see the receipt, then Submit.

Your Task

  1. Declare integer variables price = 6, quantity = 4, and discount = 3. Compute the final total using those variables, and print exactly Total: 21 followed by a newline.

Check the arithmetic

price * quantity gives 24; subtracting discount leaves 21. Print the value you calculated, not a hard-coded 21. The output check catches spelling and punctuation, but cannot tell whether you used the variables. Take a look at your expression before submitting.

Hint 1
1 / 1
HINT 1

Compute price * quantity - discount and use %d to print the integer.
