given regular expression "\d" , match each digit in "a123b456" (i.e. 1, 2, 3, 4, 5, 6). given regular expression "\d\d" , same teststring, seems match "12" , "45" - @ least http://regexpal.com/ says, regex evaluator created myself using c++ textbook (which uses boost/regex). why doesn't second 1 match "23" , "56", well, or, if behaviour correct one, why first 1 match each number? why doesn't second 1 match "23" , "56"? because that's overlapping match expecting regex give you. once part of string matched pattern, won't matched again same pattern. so, since 2 been included in previous match 12 , gone. regex move onto next character 3 . , following character, cannot see 3 included part of string matching \d\d . next substring matching pattern found @ 45 . try changing string to: "a1234b456" and 3 matches - 12 , 34 , , 45 . however, can ov

(or add path or whatever, more information here: https://code.google.com/p/selenium/wiki/chromedriver ) afterwards following example should work: from selenium import webdriver selenium.webdriver.common.keys import keys driver = webdriver.chrome() driver.get("http://www.python.org") assert "python"

i'm little confused accessor's in c#. assumed done private accessor's: private string m_name = { { return m_name; } // not sure if correct. maybe use 'this' set { m_name = value } // not sure if correct } i'm not sure if code above valid. i've not used accessors in c#. instead, documentation states this: class employee { private string m_name; public string name { { return m_name; } protected set { m_name = value; } } } why done, because perspective user can still access private m_name property via name. doesn't defeat point of private (or protected) properties? in first example shouldn't compiler know private , create methods behind scenes (as believe @ compile time)? your first example give stackoverflowexception, need either use separate member store data or use auto properties. to answer question, reason done make property readonly outside of class, allow code running in

i'm reading solution problem in book cracking coding interview (q 1.2). objective there implement function void revers(char* str) in c reverses null terminating string. the solution code looks this: void reverse(char *str) { char* end=str; char tmp; if(str) { while(*end) { end++; } end--; //code reverse } } here, str contains address right? , if(str) evaluate false if str 0 , right? so i'm saying is, there no chance str contain address 0x0000 , evaluating if(str) false ? str indeed contain address (it's pointer char ), , if(str) evaluate false iff str equal null pointer . note null pointer not required standard refer address 0 ; however, standard mandates literal value of 0 when used in pointer context must interpreted compiler address of null pointer -- whatever might be. this means test if(p == 0) guaranteed same if(p == null) . also, conditional if(p) guaranteed same if(p
