算法begin declare a poniter dr to the dir type. declare another pointer en of the dirent structure. call opendir() function to open all file in present directory. initialize dr pointer as dr = opendir("."). if(dr) while ((en = readdir(dr)) != null) print all the file name using en->d_name. call closedir() function to close the directory.end.
示例#include <iostream>#include <dirent.h>#include <sys/types.h>using namespace std;int main(void) { dir *dr; struct dirent *en; dr = opendir("."); //open all directory if (dr) { while ((en = readdir(dr)) != null) { cout<<" \n"<<en->d_name; //print all directory name } closedir(dr); //close all directory } return(0);}
