Question

Create a class called Skateboard. Skateboard has 3 private member variables and 3 public member functions.(C++, Visual Studios)

Skateboard has the following 3 private member variables:

1) the brand of the skateboard (such as “Sector 9”)

2) the model of the skateboard (such as “Hot Steppa”)

3) the length of the skateboard in inches (such as “22”)

Skateboard has the following 3 public member functions:

a member function named print which does not have any return value or input parameter. It should display to the screen all 3 member variables (use whatever format you prefer)

a member function named set which does not have any return value but has 3 input parameters which are 1) skateboard brand 2) skateboard model and 3) length of the skateboard. This function will set the value of each member variable with each parameter given.

For example, consider the following code.
Skateboard s;

s.set(“Sector 9”, “Hot Steppa”, 22);
The above line should set the three member variables’ values accordingly.

a member function named isLongBoard which returns true if the skateboard has a length of more than 28 inches. Otherwise, it returns false.

In the main function, create a vector of 4 Skateboards named skateboardCollection.

Using a for loop and cin, ask the user to enter the brand, model, and length of each skateboard and populate each element in the vector using set member function.

After that display all of the data in the vector via a well-designed loop using the print member function. Also display if the board is a longboard as determined by the isLongBoard function.
