while loop - C++ - inputting and outputting multiple integers with io redirection -


i'm new c++ , writing simple program should take integers file ints , output them formatted appropriately. issue program skips 1 of values when outputting. eg (\n representing new line) "51 123\n -10\n 153 111" come out "123\n -10\n 153\n 111\n 0". tips or pointers bettering code great. here code: 

using namespace std;  int main(int argc, char *argv[]) {     size_t i;     int n;     int a, b, c, d, e;     if (argc == 1) {         while (cin >> n) {             cin >> a;             cin >> b;             cin >> c;             cin >> d;              cin >> e;             cout << setw(10);             cout << << "\r\n";             cout << setw(10);             cout << b << "\r\n";             cout << setw(10);             cout << c << "\r\n";             cout << setw(10);             cout << d << "\r\n";             cout << setw(10);             cout << e;         }     } else if (strcmp(argv[1],"-x")==0) {         /* not used yet */     } else if (strcmp(argv[1],"-o")==0) {         /* not used yet */     } }

problem 1:

you reading number n using while ( cin >> n ). number not being written out cout. means, first number being read , discarded.

problem 2:

the line cin >> e; not read e. that's why have 0 in output.

suggested fix:

read numbers in conditional of while.

while (cin >> >> b >> c >> d >> e) {    cout << setw(10);    cout << << "\r\n";    cout << setw(10);    cout << b << "\r\n";    cout << setw(10);    cout << c << "\r\n";    cout << setw(10);    cout << d << "\r\n";    cout << setw(10);    cout << e; }

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
