这是一段VB6的代码,谁能给翻译成C语言

这个问题是问题吗， 感觉像在请枪手~``

文件中的
ifile = FreeFile
与
ReDim fst(1 To LoadFSTdata, 239)
什么意思?

[drlqyy]

Get ifile, 1 + (j - 1) * longDayFST, tempdata(j)
什么意思?

[caofusheng]

ifile = FreeFile 意思是取得一个空闲的文件号
ReDim fst(1 To LoadFSTdata, 239) 意思是重新定义数组的大小

[ZOU_SEAFARER]

Get ifile, 1 + (j - 1) * longDayFST, tempdata(j)

‘=================================================================
少了#号

[ZOU_SEAFARER]

搂住你还是把意图说明白，然后高手就直接参考你的代码写C乐
如果你这样，高手是没有耐心去理解你的代码的，再说你的代码还不完善，不过是判断而已吧

由于时间关系 和你的VB代码有错误，我大致翻了一下，LoadFSTdata中，好多数组的初始化处理没有写，
fread的读取数据的处理肯定是错误的。不过编译能通过。错误你自己修改吧。
