If you are reading a host's address from the command line, you may not know if you have an aaa.bbb.ccc.ddd style address, or a host.domain.com style address. What I do with these, is first try to use it as a aaa.bbb.ccc.ddd type address, and if that fails, then do a name lookup on it. Here is an example: Converts ascii text to in_addr struct. NULL is returned if the address can not be found.

I am including the header file <string>, and I am using the string class, but the code doesn't compile? (namespace resolution, having the std:: topics) How do I use unique() with vectors? (answered only once, but still a good question to have due to people not knowing that it's possible to do) See similar questions...

Well, printf does it for output, so look at its related function named sprintf that "prints formated output to a string." See similar questions...

It's easy. Use sprintf. For example: char string1[50]; char string2[50]; short int var1; float var2; ... sprintf (string1, "%d", var1); sprintf (string2, "%f", var2); See similar questions...

You want to make a function that converts from a type to another. Like from std::string to int, or the other way around. This can be done using std::stringstream and insertion / extraction operators. Just as above, templates will prove of great help: Its usage is not as straightforward as the above explained max template. Normally, you would want to call it like "int value = lexical_cast( myStdString );". There is, however, a problem. See similar questions...

There are two easy ways to do this: you can use the <cstdio> facilities or the <iostream> library. In general, you should prefer the <iostream> library. See similar questions...

NO. One can always book mark/ add to favorites this address by pressing Ctrl & D keys simultaneously in the Internet explorer browser with the web page displayed. Next time one can directly access this web page from the Favorites/ Bookmark menu of the Browser. Refer to the Browser Help for more details. If the Internet address is printed on your visiting card, you can refer to it anytime. See similar questions...

If your ISP or company is running the Internet Junkbuster for you, they will tell you the address to use. It will be the name of the computer it's running on (or possibly its numeric IP address), plus a port number. Port 8000 is the default, so assume this number if it is not unspecified. Sometimes a colon is used to glue them together, as in junkbuster.pro-privacy-isp.net:8000 but with most browsers you do not type the colon, you enter the address and port number separately.

In general, when you want to convert from one type to another, the first class to look at is System.Convert. It has a load of static methods which are likely to help you. If you're converting from a String, you could also check whether the type that you want to convert to has a Parse method or something similar - for instance, I usually use DateTime.ParseExact to convert from a String to a DateTime.

Some libraries have routines strupr and strlwr or strupper and strlower, but these are not Standard or portable. It's a straightforward exercise to write upper/lower-case functions in terms of the toupper and tolower macros in <ctype.h>; see also question 13.5. (The only tricky part is that the function will either have to modify the string in-place or deal with the problem of returning a new string; see question 7.5a. See similar questions...

There are several ways. The most straightforward is: String myString = numString.trim(); int i = Integer.parseInt(myString); long l = Long.parseLong(myString) or String myString = numString.trim(); i = Integer.parseInt(myString,myIntRadix); Note 1: There is a gotcha with parseInt - it will throw a NumberFormatException for String values in the range "80000000" to "ffffffff". You might expect it to interpret them as negative, but it does not. The values have to be "-80000000" . See similar questions...

Try any of these: String s = String.valueOf(i); or String s = Integer.toString(i); or String s = Integer.toString(i, radix); or // briefer but may result in extra object allocation. String s = "" + i; Note: There are similar classes for Double, Float, Long, etc. See similar questions...

OCTET STRING value like 73:63:6f:74:74:79 can be converted into a readable string (DisplayString) by formatting it according to the DisplayString textual convention. See similar questions...

The simple answer is: "It hasn't." This misconception is usually caused by the site in question having migrated to the Apache Web server software, but not having migrated the site's content yet. When Apache is installed, the default page that gets installed tells the Webmaster the installation was successful. The expectation is that this default page will be replaced with the site's real content. See similar questions...

Your web site will respond with or without the www prefix. For example, if you chose a domain name of widgets.com your site will also respond to www.widgets.com. Your site will also respond as a sub-domain of BonusPages (www.bonuspages.com/widgets) at no additional charge. Keep in mind when you select your domain name that your domain should end with .com if its a commercial site, .org if its an organization and .net if you offer internet related services.
