Problem Statement:     Location Calculation     

 

You are required to write a program for calculating location somewhere on the map. There are two parameters (coordinates) used in calculating a location. One is longitude and the other is latitude. You need to overload ++, --, new and delete operators for this.

 

Detailed Description:

 

  • You are required to create a class named Location.
  • It will have two private data member longitude and latitude.
  • These data members will be assigned values through constructor parameters. For example obj1(20,30).
  • Overloaded ++ operator will increase the both longitude and latitude values by one, overloaded -- will decrease both by one.
  • By overloading new operator, you will allocate the memory dynamically for the object of class Location.
  • The overloaded delete operator will free (de-allocate) the allocated memory.
  • You have to create two objects of class Location. One object will be created through overloaded new operator and other will be created without it.
  • A message “Overloaded new operator called”, embedded inside overloading function for new operator, should be displayed when the object is created through new operator.
  • Similarly, a message “Overload delete operator called” should be displayed upon calling overloaded function of delete operator.
  • Assign the values (10, 20) and (30, 40) for longitude and latitude for object 1 and 2 respectively.

yea wala sol kaharab hea ok.

tehreem ji thora sa kam he krny wala hai ..baki tu ye program fit hai ..wots wrong with it?
