Functions are great, they take data (input), do stuff with that data and then return it to you all shiny and fancy (output).
Below are some specifications for Functions to be built.
a
random Number valueb
random Number value- ``
This function returns the result of adding a
and b
together. Store this value in a variable named sum
.
This function returns the result of subtracting b
from a
Store this value in a variable named 'difference'
This function returns the result of multiplying b
by a
. Store this value in a variable named product
This function checks the value stored at difference
and uses this number in the string "My football team lost X times this week", where 'X' is the value stored at difference
This function checks the value stored at sum
and uses that number to print to the screen the phrase "I LOVE TO ADD" x
amount of times, where x
is the value stored at the variable sum
This function checks the value stored at product
and multiplies it by the number stored at difference
and then prints the result.
This function takes three Number arguments then adds the first two arguments together then with the sum of that operation subtract the value at the third argument. This function should make use of your previous functions.
example: addThenSubtract(4, 5, 7); //-> returns 2 because 4 + 5 - 7 = 2
This function takes three Number arguments then adds the first two arguments together then with the sum of that operation multiply it by the third argument. This function also should make use of your previous functions.
Store the return of this function to a variable named howMany
@param Datatype: String firstName
@param Datatype: String lastName
@return Datatype: String
This function takes two String arguments firstName
and lastName
. This function returns back a string which represents someone's full name.
Call this function and pass your first and last name into it. Store the return value to a variable named myFullName
@param Datatype: Number age
@return Datatype: Boolean
This function takes one Number argument age
. This function returns true
or false
if age
is lower than the legal drinking age in the state of Hawaii.
Call this function and pass in a number value. Store the return value to a variable named canDrinkBeer
This function checks the value stored at the canDrinkBeer
variable and if the value is false
it should print to a message to the screen, "The Party will have tons of Cake!" otherwise this message should be "This Party will have an open bar".
This function takes 3 arguments firstName
, lastName
, food
and prints out a message. Internally this function will make use of the createFullName
function you created earlier.
exmaple input: if someone called your program like this eatFood( "John", "Papa", "Pizza" )
example output: "John Papa loves to eat Pizza"
exmaple input: if someone called your program like this eatFood( "Peter", "Bojangles", "California Burrito" )
example output: "Peter Bojanglesloves to eat California Burrito"
This function will print to the screen X
amount of times. Where X
is the value stored at howMany
. Inside of this function it will check if the value of canDrinkBeer
, if the value is true the message will be "Bacon Pancakes, makin' Bacon Pancakes..."
othewise the message will be "Let it go.... LET IT GOOOOOOoOoOoOo..."
