Data type

6. What value is stored in uninitialized variables?

3. Write assignment statements that perform the following operations with variables a, b and c. set b = a+2 set a = b*4 set b = a/3.14 set a= b-8

4. Write assignment statements that perform the following operations with the variables a, b, and c.
a. Adds 2 to a and stores the result in b
b. Multiplies b times 4 and stores the result in a
c. Divides a by 3.14 and stores the result in b
d. Subtracts 8 from b and stores the result in at

a. Set result = x + y = 4+8= 12
b. Set result = z * 2 = 2*2= 4
c. Set result = y / x = 8/4= 2
d. Set result = y – z = 8-2= 6

5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.

Floating-point variable cost

6. Write a pseudocode statement that declares the variable total so it can hold integers. Initialize the variable with the value 0.

Declare Real price=99.95
Display "the original price."
Input item original price
Display "price"

7. Write a pseudocode statement that assigns the value 27 to the variable count.

varCount=27

8. Write a pseudocode statement that assigns the sum of 10 and 14 to the variable total. numOne=10 numTwo=14 numOne+numTwo=Total
Print.out Total 24

9. Write a pseudocode statement that subtracts the variable downPayment from the variable total and assigns the result to the variable due.

Declare Integer downPayment
Declare Integer total
Declare Integer due
Set due= total-downPayment

10. Write a pseudocode statement that multiplies the variable subtotal by 0.15 and assigns the result to the variable totalfee.
