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

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);

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)

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.

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.

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.

Converting from int to string is a little more complicated than converting a string to int. There are no standard C++ functions for this, but there is a way to do it using standard stringstreams. The class stringstream is declared in header sstream and is used like this: std::stringstream ss; std::string str; ss << 31337; ss >> str;

Often you'll want to round the real number appropriately first (round/2, floor/2, ceiling/2) rather than relying on fix's truncation. See the documentation for is/2 and fix/2.

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.

You can use the parseInt() and parseFloat() methods. Notice that extra letters following a valid number are ignored, which is kinda wierd but convenient at times.

The simplest way is to use the function int std::atoi(const char*) declared in cstdlib. For example, std::atoi("31337") returns 31337. Alternatively, you can use std::strtol() or std::strtoul(). These functions provide more functionality such as the ability to convert hexadecimal or octal number strings, and are also declared in cstdlib.

Converting from int to string is a little more complicated than converting a string to int. There are no standard C++ functions for this, but there is a way to do it using standard stringstreams. The class stringstream is declared in header sstream and is used like this:

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.

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" .

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.

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.

Use ''short'' when you need to avoid values over 32,767, ''int'' when you want to store integers, ''long'' for long numbers (more than 6 digits), and ''float'' for numbers over 4 billion.

Not exactly a text format, but also very useful: MIDINotate Musician or Composer does a surprisingly good job with converting MIDI files to printable sheet music, even if the quantization is tricky. Free 30-day trial version for Windows. If you're willing to switch to Java as your programming language you'll find it has an extensive library for parsing/generating midi files.

Here's the relationship for the most common HP-UX machines: Model number on the String returned outside of the box by uname -m ------------------- --------------- default ----------> 9000/800 E25 --------------> 9000/806 E35 --------------> 9000/816 E45 --------------> 9000/826 E55 --------------> 9000/856 F10 --------------> 9000/807 F20 --------------> 9000/817 H20 --------------> 9000/827 K400 -------------> 9000/829 F30 --------------> 9000/837 G30/H30 ---------.

To have a US item run under UK current you need to buy a transformer, a product that you plug into the wall and has a US-style jack at the other end. The transformer will "step down" in voltage from 240 to 120v. From there you may want to plug in a US-style power strip and provide current for sev eral products. Next you need to consider how many watts your transformer is providing (all transformers should clearly indicate this).

far as I know the whole representation thing went more or less something like this: She started (in 1991?) with Innovative Artists and Joan Horowitz. In 1994, she left Innovative and some time later signed with Gersh. Then a bit later (1995?) she left Joan to sign with Peg Donegan. In 1996 she left Gersh for William Morris Agency (Alyson Band). A bit later (late 1996 - early 1997?) Alyson left William Morris for United Talent Agency and Yancy left with her.

Our XML database will have up to 10,000 documents in it, each with a time stamp that is in the dateTime XML format. It's a good idea to write datetime strings along the lines of the following example so that they are valid numerical values that can be to 18:57:22 on 16 August 2004. Storing the number of seconds since the epoch (1970) as per the Unix convention is another solution. You can also convert the Integer to date types in C++, or Java, and then do a comparison, if it's easier that way.

The easiest method is to use a new version of GNU sed, ssed, sedmod or sed16 and employ the \U, \L, or other switches on the right side of an s/// command. For example, to convert any word which begins with "reg" or "exp" into solid capital letters: sed -r "s/\<(reg|exp)[a-z]+/\U&/g" # gsed4.+ or ssed sed "s/\<reg[a-z]+/\U&/g; s/\<exp[a-z]+/\U&/g" # sed16 and sedmod you can see, sedmod and sed16 do not support alternation (|), but they do support case conversion.

The ANSI mktime() function converts a struct tm to a time_t. No standard routine exists to parse strings.

These days, it's not necessary to use the Symbian cast macros (eg REINTERPRET_CAST) since these are simply defined as the equivalent C++ standard (eg reinterpret_cast). They're a legacy from when GCC didn't support the casts.
