Chapter 16, Problem 7PP

Program Plan Intro

• Include required library files.
• Define a class named “ArrOutOfRangeErr”.
• Declare the required variables, constructors and function inside the access specifier “public” and “private”.
• Define a “testExcep()” function to test the exception.
  • Using exception, set and get the values.
• Define a “create2DArr()” function to create an two-dimensional array.
• Define a “check_args()” function to check the validity and return the message if something is wrong.
• Define a “set()” function to store values.
• Define a “get()” function to retrieve the values.
• Define a default constructor for no messages.
• Define a parameterized constructor for row and column data.
• Define a “getMsg()” function to return the exception message string.
• Define a “getRows()” function to return the number of rows.
• Define a “getCols()” function to return the number of columns.
• Define a “getDesiredRow()” function to return the requested row number.
• Define a “getDesiredColumn()” function to return the requested column number.
• Define a “writeErr()” function to write the error message.
• Define a “main()” function.
  • Declare the required variables.
  • Create a 2D array for rows and columns.
  • Populate the rows and columns.
  • Print the array contents using “for” loop.
  • Then test the some boundary cases.
