Chapter 2, Problem 4C

Program Plan Intro

Pair of intersection

Program plan:

• Declare the header files and namespace.
• Create a class “Parallel”,
  • Declare the private member variable.
  • Declare the public access specifier.
  • Define the constructor to set the parallel intersection exception,
    • Set the error message.
  • Define the method “get_Message()”,
    • Return the message.
• Create a class “Line”,
  • Declare the necessary private member variables.
  • Declare the public access modifier.
  • Define the constructor “Line()” to set the initial values.
  • Define the method “intersect()”,
    • Check whether the x coordinates are equal,
      • If it is true, return the value.
• Define the “main()” method,
  • Create array object for “Line”.
  • Create necessary lines by calling the constructor necessary times.
  • Execute loop for “0” through “2”,
    • Execute loop for “0” though “m”,
      • Execute “try” statement,
        • Intersect all distinct pairs.
        • Print the output message.
      • Execute “catch” block if exception occurs,
        • Print the error message.
