CS 135 Pool

Write a class named Pool to represent a swimming pool. Start with writing a UML diagram that we develop in class as a group. The class should have:

• private data fields to store the length (in feet), width (in feet), depth (in feet), volume (in cubic feet), and a boolean field named is_empty to indicate if the pool is empty.
• A default constructor without any parameters to initialize the data field variables. Assume our default pool has a length of 10, width of 10, and depth of 5 and is empty. Note the volume is calculated as: length * width * depth
• Appropriate public methods (mutators) to set the value of each of the private data fields.
• Appropriate public methods (accessors) to get the value of each of the private data fields.
• A member function named tostring() that returns a string description of the pool. If the pool is empty, the function returns the length, width, depth, and volume in one combined string. If the pool is not empty, the function returns the length, width, depth, and volume along with the string "pool is full " in one combined string.
• Write a test program that creates two Pool objects. For the first object, create it as a default pool. For the second object, assign length of 70, width of 30, depth of 15 and assume that the pool is full. Display the objects by invoking their tostring function.

Here is a sample run for the calculations.

object 1:
Length:10
Width: 10
Depth:5
Volume: 500
object 2:
Length:70
Width: 30
Depth:15
Volume: 31500 pool is full

String concatenation:

In order to create a string that mixes strings and numbers, use the ostringstream definition.

Need:

include < sstream>
For example:
ostringstream s1;
double age = 30;
string name = "foo";
string news;
s1 << name << " is " << age << "tyears oldn";
news = s1.str(); // convert the ostringstream to a string
cout << news;
