c++ - How to read txt file into vector and cout the file? -

- 

#include <iostream> #include <fstream> #include <vector> #include <string>  using namespace std;   int main() {     vector<int> temp;      ifstream infile;     infile.open("numbers");      if (infile.fail())     {     cout << "could not open file numbers." << "\n";     return 1;     }      int data;     infile >> data;     while (!infile.eof()) {     temp.push_back(data);     infile >> data;     }      cout << data << " " << endl;    }

i trying cout numbers text file "numbers" using vector. 

15 10 32 24 50 60 25

my experience pretty nil, , guidance on why fails open helpful.

your code fine you're printing wrong thing. change bottom of main this

int data; while (infile >> data) {     temp.push_back(data); }  for( vector<int>::iterator = temp.begin(); != temp.end(); i++) {     cout << *i << endl; }

*edited after reading suggested dup.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
