the <dirent.h> library has the following functions
c Syntax (Toggle Plain Text) 
  1. int            closedir(DIR *);
  2. DIR           *opendir(const char *);
  3. struct dirent *readdir(DIR *);
  4. int            readdir_r(DIR *, struct dirent *, struct dirent **);
  5. void           rewinddir(DIR *);
  6. void           seekdir(DIR *, long int);
  7. long int       telldir(DIR *);
http://www.opengroup.org/onlinepubs/.../dirent.h.html


if you're confined to Windows-specific solutions, theres an implementation of this for Windows
http://www.gimp.org/~tml/gimp/win32/dirent.zip

if that's not acceptable for homework purposes, then maybe you can just get away with a system call like strcpy(myBigString, system("dir"));

It would be best to let us know what O/S and compiler you are using so we don't have to guess, as jephthah was forced to do. They all have different ways to accomplish the task.

Look into findfirstfile and findnextfile .
