What is the commonly accepted method for converting arbitrary objects to and from their String representations, assuming that the exact class of the object is known ? In other words, I need to implement some methods similar to the following: public interface Converter { /** * Convert this object to its String representation. ...
char *funcNames[]= {"VString","VChar","VArray","VData"}; for(int i=0;i<4;i++) { char* temp = funcNames[i]; int len = strlen(funcNames[i]); for(int j = 0;j<len ;j++) { if(j!=0) { char arr = temp[j]; } } } here i want to separate "V" from all string in char array ...and create a...
I am reading a text file which contains a word with a punctuation mark on it and I would like to read this word into a string without the punctuation marks. For example, a word may be " Hello, " I would like the string to get " Hello " (without the comma). How can I do that in C++ using ifstream libraries only. Can I use the ignore fu...

I was trying to speed up a certain routine in an application, and my profiler, AQTime, identified one method in particular as a bottleneck. The method has been with us for years, and is part of a "misc"-unit: function cwLeftPad(aString:string; aCharCount:integer; aChar:char): string; var i,vLength:integer; begin Result := aString; ...

Is there some method which can helps me? I saw in the documentation that...
Hi guys... I'm preparing for a quiz, and I have a strong suspicion I may be tasked with implementing such a function. Basically, given an IP address in network notation, how can we get that from a 32 bit integer into a string in it's dotted decimal notation (something like 155.247.182.83)...? Obviously we can't be using any type of inet...

Hey guys, I previously posted how to implement a function that will convert an integer to an IP address string. So how would we go vice-versa, that is, given a string (154.111.23.23) that is an address, how can we get that integer back, using no inet functions. ...
How can I convert the IEnumerable<char> "nonLetters" to a string[] so that I can use it with String.Join? string message = "This is a test message."; var nonLetters = message.Where(x => !Char.IsLetter(x)); Console.WriteLine("There are {0} non-characters in \"{1}\" and they are: {2}", nonLetters.Count(), message, String.J...

I have two string arrays "Array1[size]" and "Array2[size]". They both have the same size. I would like to write a function which contains this two arrays but I am having problems in the way that I am declaring them. I am declaring it like this: void Thefunction (string& Array1[], string& Array2[], int size); And when I call it I am...
I need to extract the virtual host name of a HTTP request. Since this willl be done for every request, I´m searching for the fastest way to do this. The following code and times are just some of the ways I had studied. So, there is some faster way to do this? $hostname = "alphabeta.gama.com"; $iteractions = 100000; //While Test $ti...
Let's assume I have the following file - template.php: <?php $string = 'Hello World!'; ?> <html> <head> <title>Test Page!</title> </head> <body> <h1><?= $string; ?></h1> <p>You should see something above this line</p> </body> </html> I'm aware that I can use file_get_contents() to get the conten...
When trying to compile the following: #include <string> #include <iterator> #include <iostream> using namespace std; int main() { string s(istream_iterator<char>(cin), istream_iterator<char>()); return s.size(); } g++ 4.4.1 gives me: main.cc: In function ‘int main()’: main.cc:6: error: request for member ‘size’ in ‘s’, which is o...
string.Format() with it's "bla {0} bla" syntax is great. But sometimes I don't want to enumerate the placeholders. Instead I just want to map the variables sequentially in the placeholders. Is there a library that can do that? For instance, instead of string.Format("string1={0}, string2={1}", v1, v2) something like string.Format("s...
