For loop isn't working C++ - 


#include <iostream> using namespace std;  int main()  {   char ar[4][30];   int i=0,t;   cout << "enter test cases"<< endl;   cin>>t;   for(i=0;i<t;i++)   {       gets(ar[i]);    }     return 0; }

from code want enter multiple strings. let's come problem, when enter number of test cases, ar[i] accepts 1 string less test cases.i don't understand why code isn't working. working on eclipse.

when cin >> t, there's linefeed left in input buffer that's being read, , fed firsr gets invocation.

assume user input:

2 aaa bbb

after cin >> t, input buffer is

<enter> aaa bbb

so first time call gets, reads enter , returns, ar[1] set empty string.

you add cin.ignore() or gets discard before enter (including).

    cin >> t; ->  gets(null);

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
