CPU
2) Which number system is used by a computer?
Binary system (base 2)
3) What is an object program?
An object program is a program into which some other program is translated by an assembler or a compiler
4) What is linking?
A linker combines object programs with other programs in the library to create executable code.
5) Which program loads the executable code from the main memory into the CPU for execution? The loader performs this function.

13) Design an algorithm to convert the change given in quarters, dimes, nickels, and pennies into pennies.
Let q denote the # of quarters
Let d denote the # of dimes
Let n denote the # of nickels
Let p denote the # of pennies
Get q
Get d
Get n
Get p
Number of pennies = sum (25q + 10d + 5n + p)
14) Given the radius, in inches, and price of a pizza, design an algorithm to find the price of the pizza per square inch.
Get Radius of pizza
Get Price of pizza
Price/ square inch of pizza = (price)/ (pi * Radius ^ 2)
15)The dealer's cost of a car is 85% of the listed price. The dealer would accept any offer that is at least $500 over the dealer's cost. Design an algorithm that prompts the user to input the list price of the car and print the least amount that the dealer would accept for the car.
Find user offer for car
CarCost = (0.85*listed_price)
If user offer >= 500 + CarCost then Print CarCost
If user offer < 500 + CarCost then dealer declines offer

Suppose that the tuition per semester is $25,000 and the average semester consists of 15 units. If the math class meets three days a week, one hour each day for 15 weeks, and is a four-unit course, how much does each hour of math class cost the student? Design an algorithm that computes the cost of each math class.
a) Find input for total tuition fees for semester, store as variableT for Total_tuition_fees =
($25,000)
b) Find input for total number of units taken per semester, store as variableU for
Total_units_taken = (15_units)
c) Calculate tuition fees of 1 unit in a semester by dividing the first stored variable by the second stored variable. Use the equation tuition_fee_per_unit = variableT/variableU =
($25,000/15 units)
d) Find units of the math course course_units_total = 4
e) Multiply tuition fees for 1 unit in a semester by the total course units for the math class.
Use the equation tuition_fee_per_unit * course_units_total = tuition_fee_per_course
f) Find total number of weeks the course lasts, store as variable weeks= 15
g) Find total number of days the course meets a week, store as variable days_per_week= 3
h) Find total number of hours per day that the course meets, store as
