中文字符,一个字是二个字节!

#include <stdio.h>
#include <string.h>
int main( void )
{
FILE* in;
FILE* out;
char cin;
int nLines = 0,i=0;
int bLow = 0;
if( ( in = fopen( "1.txt", "r" ) ) == NULL )
{
printf( "error can not read 1.txt.\npress any key to continue..." );
getchar();
return 1;
}
if( ( out = fopen( "2.txt", "a" ) ) == NULL )
{
printf( "error can not open 2.txt.\npress any key to continue..." );
getchar();
return 1;
}

while( !feof(in) )
{
cin = fgetc( in );
if(cin == ' ')
continue;
if(cin == '\n')
continue;

if(cin < 0)
{//是中文字符
if(bLow)
{
bLow=0;
}
else
{
nLines++;
bLow=1;
}
}
else
{
bLow=0;
if(bLow)
{
printf( "error file Fomat!" );
break;
}
nLines++;
}

if(nLines==10)
{
fputc( '\r', out );
fputc( '\n', out );
nLines=0;
}
fputc( cin, out );
}
fputc( '\r', out );
fputc( '\n', out );
fclose( in );
fclose( out );
}
