1.打開文件
char* pFileName = "test.dat";
CStdioFile f1;
if( !f1.Open( pFileName,CFile::modeRead | CFile::typeText ) ) {
#ifdef _DEBUG
afxDump << "Unable to open file" << "\n";
#endif
exit( 1 );
}

2.讀文件
char buf[100];
f1.ReadString( buf, 99 );

buf中數據為"1 2 4 6 7"

3.分離元素
int i;
int count=0;
char ch;
char xbuf[100];
memset(xbuf,0,100);
int j = 0;
for( i = 0; i < strlen(buf); i ++ ) {
ch = buf[j++];
xbuf[i]=ch;
if( ch == ' ' ) {
count++;
//此時xbuf中存了一個元素,將其賦給其它變量
memset(xbuf,0,100);
j=0;
}
}
