Input by Fastest Method

Header File:-#include<cstdio> (For c++)
#include<wchar.h> (For C)


Input for Character Variables :-

Use getchar_unlocked() for fastest input.
Eg.
char ch;
ch=getchar_unlocked();


Input for Integer Variables :-

Define a function that will take the input as:-


#define get getchar_unlocked
inline int fastinput( )
{
       int n = 0 , s = 1 ; char p = get( ) ;
       if( p == '-' ) s=-1;
     
       while( ( p < '0' || p > '9' ) && p != EOF && p != '-' )
          p = get( ) ;
       if( p == '-' )
       s = -1 , p = get( ) ;
       while( p >= '0' && p <= '9' )
       {
              n = ( n << 3 ) + ( n << 1 ) + ( p - '0' ) ;
              p = get( ) ;
       }
       return n * s ;
}
