6) Consider the function countEntries(), whose prototype follows: void countEntries (char *dirName, int *nFiles, int *nDirs) The parameter named dirName points to a character string, providing the name of a directory to be recursively explored for files and subdirectories. You may assume that dirName, and its subdirectories, contain only files and directories. After countEntries) has explored everything below the named directory, the parameters nFiles and nDirs should provide, to the calling function, the number of files and directories found, respectively. If countEntries) finds a directory that cannot be opened, it should report an error and continue its processing (i.e. the function should not exit on such an error) Write the function countEntries () in C99
