c++ - does not continue reading input from the user? -

when run program input 50000, output stops @ 633 instead of 50000, why , how fix !?? int main() { long int n; cin>>n; //n = input = 50000 double* r = new double[n]; for(long int i=0;i<n;i++) { cin>>r[i]; // each value in range 6 digits cout<<i<<" "<<r[i]<< endl; //i should stops @ 49999 } return 0; } you don't check result of cin>>r[i]; so happen cin goes fail state after getting invalid input. hit situation, no more data can retrieved cin until cin.clear() called. you should have code like if(!(cin >> r[i])) { cout << "invalid input, please try again" << endl; --i; cin.clear(); } to handle this.
