c++ - Unable to read two strings with cin.get() -

why trying input 2 strings using cin.get() fails? can read first string input fails second string , subsequent operations.. see code:

#include <iostream> #include <stdlib.h>  int main(){ long int n,k; char a[11],b[11]; cin.get(a,11);  n = atoi(a);  cin.get(b,11); cout<<b;    k = atoi(b);   cout      << "\ncin.rdstate(): " << cin.rdstate()       << "\n    cin.eof(): " << cin.eof()       << "\n   cin.fail(): " << cin.fail()       << "\n    cin.bad(): " << cin.bad()       << "\n   cin.good(): " << cin.good() << endl << endl; } 

i trying input 2 strings , store them long int variables shown in program, cin.get(b,11) fails , stack overflow occurs k= atoi(b) .also, may observe nothing output cout<<b .. and, @ last cin.fail() set 1 , means doing kind of logical error.. please me in rectifying this! please suggest method fast , meant c++ .. (if feel question bad please mention in comments before down voting this, struggling @ 21 rep!)

\n remain in buffer after first cin. can solve problem adding empty cin.get()

cin.get(a,11); n = atoi(a); cin.get(); cin.get(b,11); cout<<b;    k = atoi(b);
