How to print triple slash in codechum

The area of a triangle whose sides a, b, and c can be computed by the formula:

𝑨𝒓𝒆𝒂 𝒐𝒇 𝑻𝒓𝒊𝒂𝒏𝒈𝒍𝒆 = √𝑠((𝑠 − 𝑎)(𝑠 − 𝑏)(𝑠 − 𝑐))

where S = (a+b+c)/2. On the other hand, the hypotenuse of a right triangle can be computed using the

formula:

3. 𝐻𝑦𝑝𝑜𝑡𝑒𝑛𝑢𝑠𝑒 = √𝑎

2 + 𝑏

2 .

Write a program that can compute for the Area of a Triangle and the Hypotenuse of a right triangle. Your

program must allow the user to choose what computation to take first. Only one computation at a time. Use

a function for each computation. Allow the user to repeat the entire process as often as he/she wants

One (1) euro is equivalent to fifty five (55) pesos and one (1) dollar is equivalent to 44 pesos. Write a program

that converts dollar to euro. The program should ask the user to input an amount in dollar and display the

equivalent amount in euro. Use a function for the conversion. Allow the user to repeat as often as the user

wants.

A

method

addWin()

,

which

takes

no

arguments

and

increments

the

number

of

times

the

player has won.

•

A

toString()

method,

which

takes

no

arguments

and

returns

(as

a

String

)

the

player’s

name, followed by the number of points in parentheses.

For example, if the player’s name

is

Jeff

and the player has 25 points, you’ll return

"Jeff (25 points)"

.

note

that the auto-

grader is vary particular about the formatting of your return String here.

Getters

for

the

name

(

String

),

number

of

points

(

int

),

and

number

of

wins

(

int

).

These

should be called

getName()

,

getScore()

, and

getWins()

, respectively.

•

A method

addPoints()

, which takes in an

int

and adds that number to the total number of

points the user has.

•

A method

resetScore()

, which takes no arguments and resets the player’s score to zero.

A constructor which takes in a

String

, the player’s name.

If the

String

given is

null

or the

empty string (

""

), set the player’s name to a

unique

non-empty value (in my reference code,

I use ”Player 1”, ”Player 2”, etc).

Otherwise, set the name to the given

String

.

Score and

number of wins should both start at zero.

A constructor which takes no arguments. It sets the name to a

unique

non-empty string. (In

my reference code, I use ”Player 1”, ”Player 2”, etc).

Create a struct Boat include the length, name and how many nights the boat will be in the marina.

Ask the user for the length of the boat, the name of the boat and how many nights they will be staying. Store the info in a vector of boats but do not allow more than 20 boats because that is the capacity of the marina. Allow the user to print out all the boats that are 40 feet or above. Write a menu so the user can continue until they wish to quit.
