我正在用C ++编写一个todo列表管理器程序,并希望执行以下操作:
我尝试过使用boost/filesystem.hpp
,但似乎无法弄明白(或者如何使用g ++进行链接)。以下是我尝试过的示例(假设正确的#includes
,int main
等):
std::vector<std::string> findLists(void){
std::vector<std::string> lists;
std::string temp;
char dir[ MAX_PATH ];
std::string(dir, GetModuleFileName(NULL, dir, MAX_PATH));
dir = dir.substr(0,dir.find_last_of( "\\/" ));
path p(dir);
for(auto i = directory_iterator(p); i != directory_iterator(); i++){
if(!is_directory(i->path())){
temp = i->path().filename().string();
if(temp.compare(0,temp.find(".")+1,".txt")){
temp = temp.substr(0,temp.find("."));
}
lists.push_back(temp);
}
else{
continue;
}
}
return lists;
}
答案 0 :(得分:0)
int main(int argc, char* argv[])
{
path p (argv[1]); // p reads clearer than argv[1] in the following code
if (exists(p)) // does p actually exist?
{
if (is_regular_file(p)) // is p a regular file?
cout << p << " size is " << file_size(p) << '\n';
else if (is_directory(p)) // is p a directory?
cout << p << "is a directory\n";
else
cout << p << "exists, but is neither a regular file nor a directory\n";
}
else
cout << p << "does not exist\n";
return 0;
}
您拥有所需的所有设施。这只是一个起点,但你应该能够很快完成它。
