Math operators and a challenge

Mastery Objectives: Students will—• Be able to use augment assignment operatorsDemonstrate proficiency in using types, variables

and simple i/O

Augmented assignment operators

• Another way to write a math calculation• Less code, harder to read

Useful Augment Assignment Operators

Operator Example Equivalent*= x*=5

x=x*5/= x/=5

x=x/2%= x%=5 x=x%5+= x+=5

x=x+5-= x-=5

x=x-5

Example

food = food * 52

Or

food *= 52

Printing Strings and Numbers Together

print “Grand Total: “, total

print “Grand Total: “ + total

Programming Challenges

• Write a program that allows a user to enter his or her two favorite foods. The program should print out the name of a new food by joining the two food names together.

• Write a Tip program where the user enters a restaurant bill total. The program should then display two amounts: a 15-percent tip and a 20-percent tip.

Programming Challenges continued

• Write a Car Salesman program where the user enters the base price of a car. The program should add to the base price tax, license, dealer prep, and destination charge. Make tax and license a percent of the base price. The other fees should be set values. Display the actual price of the car once the extras are applied.

How to turn in Challenges

• Make sure to comment in your name• Print out a copy of the code and the output• Staple both copies together: code first, output

second• Turn in all three challenges as a packet using a

paper clip to clip them all together.
