C 通过函数的文件*数组：文件*还是文件**？

我正在尝试制作一个可以同时处理多个不同文件的程序。我的想法是创建一个包含20个文件*的数组，以便在达到此限制时，能够关闭其中一个文件并打开请求的新文件。 为此，我考虑了一个函数，它选择一个选项并调用另一个选项，从而完成保存（写入）、关闭和打开的工作。 在网上搜索了半个星期并做了一些证明后，我制作了两个版本，一个是FILE*版本，另一个是FILE**

我的问题是：如果其中一些函数有我无法检测到的错误，或者在传递这两个函数时指针使用不当

（我显示的代码一个接一个地包含两个函数的两个版本。）

MyProgram（）{
#包括
#包括
#包括
/*myFile1a.dat、myFile2b.dat……的内容只有5个整数*/
/*没有指针到指针的版本*/
作废fReadFile（文件*pfFile[]）{
int i=0，j=0；
int iNums[15]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}；
int iNums2[15]={5001、5002、5003、5004、5005、2033、2066、2099、2133、2166、3001、3002、3003、3004、3005}；
char cNameFile4d[32]=“myFile4d.dat”，cNameFile5e[32]=“myFile5e.dat”；
char cNameFile6f[32]=“myFile6f.dat”；
char cNameFile[32]={“}；
int iResultFclose=0；
对于（i=0；i单个文件句柄是指向
file
的指针，即
file*
。由于需要这些
file*
元素的数组，因此指向数组的指针是
file**arr
，相当于
file*arr[]
当用作函数的参数类型时。
编译并调试以查看任何错误。您是否要求查看代码以帮助诊断潜在问题？我无法想象为什么要使用
（文件**）[
。a
（文件*）[]
应该足够了。至于检查代码是否存在问题，您在错误的位置发布了。您需要。我还没有阅读代码，但请注意，
FILE*pfFile[]
相当于
FILE**pfFile
，它基本上是指向文件（2D文件数组）的指针。
FILE**pfFile[]
是一个3D数组。基本上，一个文件指针数组就是您所需要的。当发生数组到指针的转换时，它是等效的，否则它们是两种不同的类型。
