so code did: #include <stdio.h> #include <stdlib.h> int main() { char playername; int playerage; printf("what's name, , age?\nyour name: "); scanf("%s\n", playername); printf("your age: "); scanf("%d\n", &playerage); printf("okay %s, %d years old!", playername, playerage); return 0; } and everytime run it, after input name crashes , don't know how fix it. these 3 things appear when closes: format '%s' expects argument of type 'char *', argument 2 has type 'int' [-wformat]| format '%s' expects argument of type 'char *', argument 2 has type 'int' [-wformat]| 'playername' used uninitialized in function [-wuninitialized]| what mistake? scanf("%s\n", playername); wrong because %s call char* data playername here type char . you have make playername array of characters , set max length of input avoid buffer overflow. #in...

recently i've put computer sleep, , when started up, computer turned off. before open file, asks me encoding. i've tried multiple, , auto-detect. no luck. later when turned on, mainwindow. xaml looked this: the mainwindow. xaml.cs surprisingly fine, , registers variables written in xaml file. other xaml files in project fine. when hover on lines, error shows: the value "□" not valid character does know if mainwindow.xaml salvageable or lost cause? thank lot answers. clear shadow cache , restart visual studio. should fine. shadow cache located at c:\users\username\appdata\local\microsoft\visualstudio\12.0\designer\shadowcache delete shadow cache corresponding visual studio version , restart it. should working fine.

i trying compare 2 arrays. 1 array array of person objects, each of has email property string email address. other array emailaddress object has descriptive word "work" or "personal" , actual string email address. basically both objects have string property email address. want compare these arrays of objects see if 1 of objects each array has same email address. right using nested for loops shown below taking long. for person in self.allpeople! { e in emailaddresses! { if e.value == person.email { return true } } } i thought using set intersection looked work comparing same objects , not object's properties. thanks. you can still use set functionality first creating set of emails. map helps turn 1 collection another, in case changing collection of allpeople collection of people's email s. faster because emailaddresses iterated once, instead of once per person . let personema...

we're writing code match submissions people. given first name, last name, etc. try narrow down single result. however, submissions addresses or other contact info might spelled wrong, prefer match on few criteria possible--hence multiple steps finding match. here's algorithm: count first name , last name if count == 1 // done if count > 1, count first name, last name, email if count == 1 // done // etc. what best way tell if we'll 1 person result or not given query? the obvious answer count, unnecessary since don't need number, need see if it's plural results or singular result (the matching may bad enough return count of thousands). option limit 2 results, minimizes counting, adds confusing code (why count if it's limited well?) is there preferred method doing this? mysql not have function tell if have 1 match or more. options, said, count(*) or use limit 2 . the limit option should faster execute, going assume performance differe...
