Write a class “Line” with following
specifications
• three data members, endp1, endp2 and char
pointer linetype (Give any character value in linetype e.g B implies bold line,
N implies normal line and S implies straight line)
• default constructor with default arguments
• copy constructor
• Write getter & setter functions.
• calculateLength method which calculates the
length of the line
• compareLine method which compares two line
objects and tells which line is longer (use this pointer to use the current
objects data members, you can pass 2nd object in the parameter of
this function)
• In main program
} Create line1 object so that default
constructor is called
} Create line2 object using line1 object (copy constructor must be called)
} Calculate the length of each line object and
compare them by calling functions.
