i created function insert data bst , works fine. used "pass reference" , value of "head" supposed change after each insertion. however, found "head" pointing first value inserted. here explain causes "head" point first data inserted? void insert(node *&head, int val){ if(head == null){ head = newnode(val); } else{ if(val <head->data) insert(head->left,val); else insert(head->right,val); } } that how function should work, head should never change or lose track of tree root. as long have head pointing @ root, have access whole tree. the reason why value not changing is, when writing insert(head->left,val); you not assigning new value head , passing reference left child next function call.

say taking string in , want check whether or not has capital letter in string. input string file. how go breaking down check see if has uppercase value using ascii values? thanks! you can use c++ algorithm library find if string contains uppercase value in using predicate (using wrapper version of std::isupper): #include <algorithm> #include <iostream> #include <string> #include <cctype> bool isupper (char c) { return std::isupper(c); } bool hasuppercase (std::string str) { std::string::iterator = std::find_if(str.begin(), str.end(), isupper); if (it != str.end()) { return true; } else { return false; } } int main() { std::string s = "this contains uppercase character in it..."; if (hasuppercase(s)) { std::cout << "string s contains least 1 uppercase character." << std::endl; } else { std::cout << "string s not contain uppercase c...

i trying read in file of data, approx 2000 lines, file looks like 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 2.1 2.2 2.3 2.4 2.5 there blank (white space) , 1.3/1.7 in same column the way have setup storing vector of structs where struct num { double d1, d2, d3, d4, d5; }; what trying achieve is num a; vector<num> data (int = 0; < 4; i++) { file >> a.d1 >> a.d2 >> a.d3 >> a.d4 >> a.d5; data.push_back(a); } and find logic recognize blank space in second line , store d1=1.6, d2=0, d3=1.7 etc.. , third line d1=2.0 , d2,d3,d4,d5=0 confused on how test/get logic implementing this, if possible in c++ vs2010 after looking @ first answer thought should provide more info, each line in file belongs satellite, , each number represents observation on specific wavelength, if blank means has no observations on wavelength. so elaborate, first line represents satellite 1 has observation on 5 wavelengths, line 2 reprsents satelit...

is there way determine "how" app launched or made active (i.e. homescreen tap, 4 finger swipe, siri, etc...)? there's thread similar ( determining whether ios application launched via siri ), not many answers in this. there's mac osx ( how can mac app determine method used launch it? ) need similar ios. i've skimmed through ( https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphoneosprogrammingguide/managingyourapplicationsflow/managingyourapplicationsflow.html#//apple_ref/doc/uid/tp40007072-ch4-sw3 ) though coudn't find recognizes "how" app launched. thanks in advance. you can figure out app launched url in application using appdelegate method: - (bool)application:(uiapplication *)application openurl:(nsurl *)url sourceapplication:(nsstring *)sourceapplication annotation:(id)annotation { } additionally, application:didfinishlaunchingwithoptions: has options, keys can find here te...

this program gets numeric values web each of values in @values array want these values printed out in table looks like il9 il8 il7 2012 v1 b1 2011 v2 b2 2010 v3 b3 . . 2000 v12 b12 where v1 .. v12 values first variable in @values etc. here program please me structure it. there escape character take me first line of program in perl thanks #!/usr/bin/perl -w use strict; use lwp::useragent; use uri; $browser = lwp::useragent->new; $browser->timeout(10); $browser->env_proxy; open(out, ">out"); $i = 2013; while ($i-- > 2000){print out "$i\n"} $a = 2013 ; $base = 'http://webtools.mf.uni-lj.si/public/summarisenumbers.php'; @values = ('il9', 'il8', 'il6' ); foreach $value (@values) { print out "$value \n" while ($a-- > 2000){ $b = $a + 1; $c = $b + 1; $query = '?query=('.$value.')...

i have 2 arrays abc[100] , def[1000] , have find array xyz[100] , xyz[i] = mindistance(abc[i],def) i.e every element in abc have find corresponding nearest element in def , set in xyz. for using threads @ 2 level . @ first level creating threads every 10 points in abc , @ second level each creating child threads every 100 points in def. below implementation . my questions how can wait child threads of abc (i.e def threads) . have gone through java join method not able figure out on how use . can use cyclic barrier in case. the actual data in magnitude 1000s abc , 10000 def , haven't used threads before ,so there issues can happen implementation . have seen use of threadpoolexecutor instead of fixedthreads in examples couldnt figure out how threadpoolexecutor have. 1. distancecalculation public class mindistancecalculation { public static list<double[]> xyz = new vector<double[]>(); public void method1(){ double[][] ab...
