我想统计文件中 中英字符出现的频数 和 保存字符
并且 是用一个结构体 保存 字符和频数，因为汉字是两个字符表示的，但我用fgetc读取时，对汉字来说就不合适。
如果用fgets的话读取的是字符串 又如何分出 汉字和英文字符呢？
------解决思路----------------------
记得以前好像做过类似的东西， 没记错的的话汉字两个字节的ascii值的最高位都是1，楼主可以根据判断字符的asii码值对获取的字符串所有字符进行判断，应该可以

Stream I/O
These functions process data in different sizes and formats, from single characters to large data structures. They also provide buffering, which can improve performance. The default size of a stream buffer is 4K. These routines affect only buffers created by the run-time library routines, and have no effect on buffers created by the operating system.
Stream I/O Routines
Routine Use
clearerr Clear error indicator for stream
fclose Close stream
_fcloseall Close all open streams except stdin, stdout, and stderr
_fdopen, wfdopen Associate stream with handle to open file
feof Test for end of file on stream
ferror Test for error on stream
fflush Flush stream to buffer or storage device
fgetc, fgetwc Read character from stream (function versions of getc and getwc)
_fgetchar, _fgetwchar Read character from stdin (function versions of getchar and getwchar)
fgetpos Get position indicator of stream
fgets, fgetws Read string from stream
_fileno Get file handle associated with stream
_flushall Flush all streams to buffer or storage device
fopen, _wfopen Open stream
fprintf, fwprintf Write formatted data to stream
fputc, fputwc Write a character to a stream (function versions of putc and putwc)
_fputchar, _fputwchar Write character to stdout (function versions of putchar and putwchar)
fputs, fputws Write string to stream
fread Read unformatted data from stream
freopen, _wfreopen Reassign FILE stream pointer to new file or device
fscanf, fwscanf Read formatted data from stream
fseek Move file position to given location
fsetpos Set position indicator of stream
_fsopen, _wfsopen Open stream with file sharing
ftell Get current file position
fwrite Write unformatted data items to stream
getc, getwc Read character from stream (macro versions of fgetc and fgetwc)
getchar, getwchar Read character from stdin (macro versions of fgetchar and fgetwchar)
gets, getws Read line from stdin
_getw Read binary int from stream
printf, wprintf Write formatted data to stdout
putc, putwc Write character to a stream (macro versions of fputc and fputwc)
putchar, putwchar Write character to stdout (macro versions of fputchar and fputwchar)
puts, _putws Write line to stream
_putw Write binary int to stream
rewind Move file position to beginning of stream
_rmtmp Remove temporary files created by tmpfile
scanf, wscanf Read formatted data from stdin
setbuf Control stream buffering
_setmaxstdio Set a maximum for the number of simultaneously open files at the stream I/O level.
setvbuf Control stream buffering and buffer size
_snprintf, _snwprintf Write formatted data of specified length to string
sprintf, swprintf Write formatted data to string
sscanf, swscanf Read formatted data from string
_tempnam, _wtempnam Generate temporary filename in given directory
tmpfile Create temporary file
tmpnam, _wtmpnam Generate temporary filename
ungetc, ungetwc Push character back onto stream
vfprintf, vfwprintf Write formatted data to stream
vprintf, vwprintf Write formatted data to stdout
_vsnprintf, _vsnwprintf Write formatted data of specified length to buffer
vsprintf, vswprintf Write formatted data to buffer
When a program begins execution, the startup code automatically opens several streams: standard input (pointed to by stdin), standard output (pointed to by stdout), and standard error (pointed to by stderr). These streams are directed to the console (keyboard and screen) by default. Use freopen to redirect stdin, stdout, or stderr to a disk file or a device.
Files opened using the stream routines are buffered by default. The stdout and stderr functions are flushed whenever they are full or, if you are writing to a character device, after each library call. If a program terminates abnormally, output buffers may not be flushed, resulting in loss of data. Use fflush or _flushall to ensure that the buffer associated with a specified file or all open buffers are flushed to the operating system, which can cache data before writing it to disk. The commit-to-disk feature ensures that the flushed buffer contents are not lost in the event of a system failure.
There are two ways to commit buffer contents to disk:
Link with the file COMMODE.OBJ to set a global commit flag. The default setting of the global flag is n, for “no-commit.”
Set the mode flag to c with fopen or _fdopen.
Any file specifically opened with either the c or the n flag behaves according to the flag, regardless of the state of the global commit/no-commit flag.
If your program does not explicitly close a stream, the stream is automatically closed when the program terminates. However, you should close a stream when your program finishes with it, as the number of streams that can be open at one time is limited. See _setmaxstdio for information on this limit.
Input can follow output directly only with an intervening call to fflush or to a file-positioning function (fseek, fsetpos, or rewind). Output can follow input without an intervening call to a file-positioning function if the input operation encounters the end of the file.
