Question

Given the following date class interface: class date {private: int month;//1 - 12 int day;//1 - 28. 29. 30. 31 depending on month & year int year;//4-digit, e.g.. 2017 public: date();//Default constructor (investigate; find what it is used for)//Postcondition: the newly declared date object is initialized to 01/01/2000 date(int mm, int dd, int yyyy);//Second constructor//Postcondition: the newly declared data object is initialized to mm/dd/yyyy void setDate(int mm. int dd. int yyyy);//Postcondition: set the contents of the calling date object to the values passed to the function void displayDateV1();//Postcondition: display the calling date object in mm/dd/yyyy format, e.g., 02/22/2017 void displayDateV2();//Postcondition: display the calling datecobject in the format like: February 22. 2017 int compareDates(date &dObj);//compares the two date objects: the calling one the dObj that is passed to the function//Postcondition: returns - 1. 0. or 1 if the calling date object if less than, equal to, or greater than dObj. respectively.}; Your are asked to: Implement all six member functions: Write a main() function containing C++ code to test all six member functions. Note that for the compareDates function, you must test all three possibilities! Format you program output so make it easily readable.

#include <string.h>
#include <stdio.h>

char string1[] = "2012-12-06 14:28:51";
char string2[] = "2011-12-06 14:28:51";

int main( void )
{
   char tmp[20];
   int result;

   printf( "Compare strings:\n   %s\n   %s\n\n\n", string1, string2 );
   result = strcmp( string1, string2 );

   if( result > 0 )        strcpy( tmp, "greater than" );
   else if( result < 0 )   strcpy( tmp, "less than" );
   else    strcpy( tmp, "equal to" );

   printf( "   strcmp:   String 1 is %s string 2\n\n", tmp );

   return 0;
}
