Their thinking ：

Because the title requires to be in front of the output value , If there are extra spaces, use 0 To make up for
Complement method ：
Try to use C In language printf ( ) function ,
Because you can format and control the format of input and output ,
and C++ The input / output stream in does not have this function ,
Although it can be achieved ,
But relatively speaking, it is more complicated
namely ：
%0nd
there 0 Is to use numbers 0 Instead of spaces

Reference code ：

#include<bits/stdc++.h> 

using namespace std;

int main( )
{
    int year = 0,month = 0,date = 0;
   
    //cin >> month >> "/" >> date >> "/" >> year ;
    /* You cannot use the above method to input  / */
    
    scanf("%d/%d/%d",&month,&date,&year);
    printf("%04d%02d%02d",year,month,date);
    
    return 0;
}
