  • In a class named Program8, write codes as follows:
  • Declare a global integer variable called length and initialize it with zero as a default value.
  • (Difficulty: easy) Write a method called setLength which accepts an integer input num and counts how many digits this number has and sets the global variable length with the result. This method does not return anything, instead it assigns a new value into the global variable length. This method should also work with negative numbers. You are not allowed to use other classes such as String, or Integer. You must use a while loop in order to count the digits.

When you are done with the method, compile your code, and use the following calls inside the interaction panel to test your method:

Program8.setLength(0); Program8.length    -> 1

Program8.setLength(-123); Program8.length -> 3

Program8.setLength(1250); Program8.length -> 4

* There is no semicolon after Program8.length since you want to see the value.

You can also write a main method and test your method by calling it inside the main method and printing the variable length to see its value.

    Write a class called Shelf that contains instance data that represents the length, breadth, and capacity of the shelf. Also include a boolean variable called occupied as instance data that represents whether the shelf is occupied or not. Define the Shelf constructor to accept and initialize the height, width, and capacity of the shelf. Each newly created Shelf is vacant (the constructor should initialize occupied to false). Include getter and setter methods for all instance data. Include a toString method...

    Write C++ code that creates an integer variable called number. Dereference a given pointer gPointer and places that value into the variable number. The pointer gPointer will have been declared and set to point to a value before your code runs. Your code will be placed inside the main function with all the appropriate #includes. After your code runs, the test case will execute the following code: cout << "number = " << number << endl; For example: Test Result...
