Analyzer: windows-make: On the Analyzer in the C language: we could scope which info we can see.

in this situation,

1. you could find index 0 to size.
2. so, getchar must know about start of file point in C language.
3. we use better a type of structures for analyzer.

so, the function lootin is like the below.

char getchar( FILE fp, int *file_index, int file_end);

char getchar( FILE fp, int *file_index, int file_end)
{
	
}

*3)
typedef struct {
	FILE *fp;
	FILE *fp_start;
	int	file_index;
	int	file_end;
} FILE_ANALYZER; 

// return:
// 0 not ascii
// a - Z
char getchar( FILE_ANALYZER *fa)
{
	return 0;
}
