ruby - Iterating over every name in a nested hash in array -


i have:

students = [   {name: "dr. hannibal lecter", cohort: :november},   {name: "darth vader", cohort: :november},   {name: "nurse ratched", cohort: :november},   {name: "michael corleone", cohort: :november},   {name: "alex delarge", cohort: :november},   {name: "the wicked witch of west", cohort: :november},   {name: "terminator", cohort: :november},   {name: "freddy krueger", cohort: :november},   {name: "the joker", cohort: :november},   {name: "joffrey baratheon", cohort: :november},   {name: "norman bates", cohort: :november} ]

i attempted iterate on every student's name in loop:

def print_loop(students)   puts "would list students? 'y/n'"   answer = gets.chomp   while answer != "n"     = students[-1]     students.each |student, value|       puts student[:name]       break if       if answer == "y"         exit       end     end   end end

it iterates , loops on first name. how iterate on every name? doing wrong?

if have use while loop, can use incrementing counter , loop while counter less size of array

i = 0   while < students.size   puts students[i][:name]   += 1 end

note idiosyncratic in ruby , use #each loop.

if want use while loop allow user request continue after every name...

i = 0 puts "would list students? 'y/n'" answer = gets.chomp while answer == 'y'   puts students[i][:name]   += 1   puts "keep going? 'y/n'"   answer = gets.chomp end

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
