   E. 2, 4, 1, 3
--------------------
Explanation:
--------------------
   a- setfill(*) -> 2- set the fill character to a character
       sets the fill character by the specified character in this case it is *
  
   b- setprecision(n); -> 4- set floating point precision to n places ?
       sets the floating point precision by n digits, for example 3.126 if precision is 2 then
       value is 3.13 after precision set.
      
   c- setisosflags(flag); -> 1- set the format flags
       sets the format flags, used to represent for hexadecimal values
  
   d- setw(n) -> 3- set field width to n
       set the width to n positions, For example if you specify
       setw(3) and cout<<"7";
       It will print 3 spaces followed by 7 on console.
