How many data types in c++?&answer address of" datastructers in c++" website?

There are five data types for C: void, integer, float, double, and char.\n\nvoid: associated with no data type \nint: integer \nfloat :floating-point number \ndouble :double precision floating-point number \nchar: character \n\n\n\nC++ defines two more: bool and wchar_t.\n\nbool: Boolean value, true or false \nwchar_t: wide character

I'll put a bit of more information than the previous two answers.. or it'll seem like I'm answering for 2 points ;-)\n\nA for loop in C++ basically has the syntax:\n\nfor([initializations];[condition check];[updates])\n{\n  //statement1;\n  //statement2;\n}\n\nInitializations: Initialize counters, iterators.. any data to be set or reset before the loop starts executing. Multiple initialization statements can be provided in a comma-separated-list.\n\nCondition Check: While the condition is true, keep iterating through the loop. Dont make this a list.\n\nUpdates: Update iterators, indices, counters etc. which need to be updated with every iteration of the loop. Again this can be a comma-separated-list.

If you develop the C++ dll, then wrap your function declaration with an extern "C" declaration.\n\nIf not, then you may use the Windows API functions GetProcAddress to look for the address, cast the result to a pointer to function then call.\n\nPls state if you have control over the C++ source and we will follow one or the other path.

there is no "code" for it. The compiler evaluates it at the compile time, and replaces with the actual number.\nThere is no way to write a function that would did that at run time, because at run time, there is not type information available - only addresses of variables not their sizes

Have your seen the "Game Programming Beginners Guide" http://www.gamedev.net/reference/programming/features/davegpg/\nI not used this class library, but you should look for a \ngame class library. \nTheatrix: A C++ Game Class Library\nhttp://www.ddj.com/184409695

GCC is a C compiler - if you're writing C++ code, you probably want to use G++, which is a C++ compiler.\n\nTo allocate an array of int's in C++, you can either use the traditional C syntax and malloc()/free() like:\n\nint* intArray = (int*) malloc(10*sizeof(int));\n...\nfree(intArray);\n\nor you can use the C++ new operator and new/delete like:\n\nint* intArray = new int[10];\n...\ndelete[] intArray;

Microsoft .Net Framework SDK has a C++ compiler. It is available in 32 and 64 bit editions.\nIts free.

With GCC compiler (used by Dev-++) you can write:\n\nsystem("cls");

Obviously, the g++ front end is available, but that\ndoesn't strike me as being particularly easy to integrate\ninto another application.\n\nAt reference #1 (below), there's an extension called\nGCC-XML which parses C++ and produces parse trees in XML\nformat (which would be *much* easier for your application\nto process).  Maybe that's a closer fit.

The sizes of float, int, long, double, etc. are one of those things that are left up to the compiler designer.\n\nHere are the rules for Micrsoft C++ 6.0 as listed in the help file:\n\n\nchar, unsigned char, signed char  -- 1 byte \nshort, unsigned short -- 2 bytes \nint, unsigned int -- 4 bytes \nlong, unsigned long -- 4 bytes \nfloat -- 4 bytes \ndouble -- 8 bytes \nlong double -- 8 bytes \n\n\nYou can see that an int and a long are both 32 bits.\n\n\nIt also gives this information on precision:\n\nNumber of digits, q, such that a floating-point number with q decimal digits can be rounded into a floating-point representation and back without loss of precision.\nfloat -- 6\ndouble -- 15\nlong double -- 15

Another answer suggested you could write your own\ncomplex functions, and while strictly possible, puts\na lot more burden on you than you might want.  There's\nvery little reason to reinvent the wheel.\n\nThe good news is that complex numbers are supported\nby both the current C ("C99) and C++ ANSI/ISO standards.\nSo if you have a recent compiler, you will just be\nable to use the complex type.\n\nIn the C++ standard, see chapter 26 (specifically 26.2).\nThe header is <complex>, and all of the expected operators\nare provided.\n\nIn the C standard, see section 7.3.  The header is\n<complex.h>, and it uses the new built-in type "complex"\nto provide all of the functions that used to only\nbe provided for float and double.

To learn the data structures of C and / or C++ take a look at some of the tutorials below and elsewhere on the web.

The Standard Template Library (STL) uses many of the extensions that the ANSI/ISO committee has made to templates, and g++ doesn't support some of these yet.  So if you grab HP's free implementation of STL it\nisn't going to work.  However, starting with libg++-2.6.2 libg++ contains a hacked version of STL, based on work by Carsten Bormann,which permits g++ to compile at least the containers.  A full implementation is going to need improved template support, which will take a while yet (2.8.0 will compile the HP version successfully,\nexcept for a couple of easily fixed places where the HP code violates the draft standard).Some say that the hacked STL and gcc-2.7.2 work quite well. Almost all of the ObjectSpace examples (a set of over 200 simple examples of STL usage) now work.\n   There are several commercial suppliers of STL implementations;ObjectSpace's version supports gcc-2.7.x. M.Khan has produced an "STL newbie guide" with lots of information on using STL with gcc.  See `http://www.xraylith.wisc.edu/~khan/software/stl/STL.newbie.html'
