thank kelly

looks you're on windows os

  1. .csv file extension not executable one. won't "executed", if present in current working directory/folder.

probably want .exe, .com or .bat file.

here, in case think want .cpp 's executable command line argument.

may like

c:\users\ms>c:\test\sp.exe c:\test\sp.csv' considering c++ file name sp.cpp

2 . looks want display out contents of sp.scv

you may want read header first (i.e titles), , read values. there lot of question asked on stackoverflow, related this, please refer them.

also proper formatting may want use std::setw

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...
