C++ Code To Print The Number Of Months And Days Between Two Dates In a Year::

C++  Code To Print The Number   Of    Months  And   Days Between Two Dates  In  a Year(Used  in labrary Applications )

=============================================================================

 #include <iostream>

using namespace std;
int main()
{
    string Mname;
    // month,day,year decraring
    int day,month,year,day2,month2,year2;
    // others stuff used in the programe:
    int sub,Maxday;
   


    cout << "\nEnter Start  Date======= \n\n" << endl;
    cout<<"\nEnter Day : ";
    cin>>day;
    cout<<"\nEnter Month : ";
    cin>>month;
    cout<<"\nEnter Year : ";
    cin>>year;

    cout << "\nEnter End  Date  ======= \n\n" << endl;
    cout<<"\nEnter Day : ";
    cin>>day2;
    cout<<"\nEnter Month : ";
    cin>>month2;
    cout<<"\nEnter Year : "<<year<<endl<<endl;
    year2=year;


    // findind the max date possible in starting month



    if (  // checking the starting month
      ((day<=31 && (month==4||month==6||month==9||month==11))||
       (day<=30 && (month==1 || month==3 || month==5 || month==7 || month==8 || month==10 || month==12)) ||

       (day<=28 && (month==2)&&(year%4!=0)))

       &&
       // if year 2 = year 1 then month 2 must greater than month 1
      (
       ( (year==year2) && (month2>month) )
       ))
    {
for(int i=month;i<=month2;i++){

// month finding

switch(i){

    // maximum days in a month::

if(month==4||month==6||month==9||month==11)    {Maxday=30;}

// for starting month

if(i==month){

}

// for last month

else if(i==month2)
        {sub=day2;}

cout<<sub<<" days in the month of "<<Mname<<" ,"<<year<<"\n";
}

}
else{
cout<<"\nPlease Recheck Your Dates  !!\n\n";
}
}

NOTE

==============

• THIS PROGRAME CAN FIND ONLY NUMBER OF DAYS AND MONTHS  INBETWEEN THE DATES IN THE SAME YEAR.

• END MONTH SHOULD BE GREATER THAN START MONTH

• I  WILL BE PUBLISHING  THE CODE FOR FINDING THE NUMBER OF DAYS AND MONTH  IN  DIFFERENT YEARS  SOON!

• FOR MORE HELP  , PLEASE   PUT A COMMENT  BELOW.
