Output date display problem in C + + (do not use printf): Programming questions #4:tomorrow never knows?

Because you can not use the printf function, but also cry, good, directly explain the idea: the topic said can be used Setfill and SETW control, that should be able to solve the problem:

Direct Sticker Code:

1#include <iostream>2#include <stdio.h>3#include <iomanip>4#include <string.h>5 using namespacestd;6 BOOLIsleapyear (intYear ) {7     BOOLIsleap =false;8     if(Year% -==0)|| (Year%4==0&& Year% -!=0))9Isleap =true;Ten     returnisleap; One } A  - intMain () { -     intYear , month, day; thescanf"%d-%d-%d", &year, &month, &Day ); -  -     intmonth_data[ A] = { to, -, to, -, to, -, to, to, -, to, -, to}; -  +     if(Day >= month_data[month-1]){ -         if(Month = = A ){ +year++; Amonth =1; atDay =1; -         } -         Else if(Month = =2 ){ -             if(Isleapyear (year) && day = = -) -Day = in; -             Else{ inmonth++; -Day =1; to             } +         } -         Else{ themonth++; *Day =1; $         }Panax Notoginseng  -     } the     Else +day++; ACOUT&LT;&LT;SETW (4) <<year<<"-";//Set the output character width to 4, and then output "-" theCOUT&LT;&LT;SETW (2) <<setfill ('0') <<month;//here Set the output character width to 2, if the number of characters is not enough, 0 will be added +cout<<"-"&LT;&LT;SETW (2) <<setfill ('0') <<day<<endl;//here first print "-", and then output character width of 2, insufficient to be supplemented by 0.  -     return 0; $  $}

No Baidu to solve the method, I am also considered original.
