Tetris The Tetris game is one of the most popular computer games ever created. The original game was designed and programmed by a Russian programmer Alexey Pajitnov in 1985. Since then, Tetris is available on almost every computer platform in lots of variations. Tetris is called a falling block puzzle game. In this game, we have seven different shapes called tetrominoes: S-shape, Z-shape, T-shape, L-shape, Line-shape, MirroredL-shape, and a Square-shape. Each of these shapes is formed with four squares. The shapes are falling down the board.

C strings and C++ strings A C string is usually declared as an array of char. However, an array of char is NOT by itself a C string. A valid C string requires the presence of a terminating null character (a character with ASCII value 0, usually represented by the character literal '\0'). Since char is a built-in data type, no header file is required to create a C string.

- When to Begin House Training Puppy. Experts recommend that you begin house training your puppy when he is between 12 weeks and 16 weeks old. At that point, he has enough control of his bladder and bowel movements to learn to hold it.f your puppy is older than 12 weeks when you bring him home and he’s been eliminating in a cage (and possibly eating his waste), house training may take longer. You will have to reshape the dog ’s behavior -- with encouragement and reward.

- EXTERNAL NAME 'CS!xyz!source.cpp'; The C or C++ files can reside on the server or the client. The server will call for the transfer of client-resident files as needed to satisfy input requirements for the CREATE PROCEDURE or REPLACE PROCEDURE request. Source files must be encoded as ASCII (workstation) or EBCDIC (mainframe), no matter what the current session character set is.

nullptr (C++ Component Extensions) The __nullptr keyword is a Microsoft-specific keyword that has the same meaning as nullptr, but applies to only native code. If you use nullptr with native C/C++ code and then compile with the /clr compiler option, the compiler cannot determine whether nullptr indicates a native or managed null pointer value.se nullptr with either managed or native code. The compiler emits appropriate but different instructions for managed and native null pointer values. For information about using the ISO standard C++ version of this keyword, see nullptr.

- Func is a delegate (pointer) to a method, that takes zero, one or more input parameters, and returns a value (or reference). Predicate is a special kind of Func often used for comparisons. Though widely used with Linq, Action and Func are concepts logically independent of Linq. C++ already contained the basic concept in form of typed function pointers. Here is a small example for Action and Func without using Linq:

TRUNC Function (DAX) A whole number. TRUNC and INT are similar in that both return integers. TRUNC removes the fractional part of the number. INT rounds numbers down to the nearest integer based on the value of the fractional part of the number. INT and TRUNC are different only when using negative numbers: TRUNC(-4.3) returns -4, but INT(-4.3) returns -5 because -5 is the smaller number.

- C++ Library The C++ library supplied by IBM and this manual is based on the Dinkum C++ Library and the Dinkum C++ Library Reference. Use of this Dinkum C++ Library Reference is subject to limitations. See the Copyright Notice (page 429) for detailed restrictions. A C++ program can call on a large number of functions from the Dinkum C++ Library, a conforming implementation of the Standard C++ library. These functions perform essential services such as input and output. They also provide efficient implementations of frequently used operations. Numerous function and class definitions accompany these functions to help you to make better use of the library. Most of the information about the Standard C++ library can be found in the descriptions of the C++ library headers (page 5) that declare or define library entities for the program. The Standard C++ library consists of 53 headers. Of these 53 headers, 13 constitute the Standard Template Library, or STL. These are

sort -g Sort numerically, using the standard C function `strtod' to convert a prefix of each line to a double-precision floating point number. This allows floating point numbers to be specified in scientific notation, like `1.0e-34' and `10e100'. Do not report overflow, underflow, or conversion errors.

- The C++ standard namespace. In ANSI C++ the standard library facilities (like cout, string, etc) are kept inside the namespace called std, which by default isn't consulted. Explicitly mention the namespace each time you use a facility - by using std::cout, etc.

- Fast ceiling of an integer division in C / C++. up vote 96 down vote favorite. 25. Given integer values x and y, C and C++ both return as the quotient q = x/y the floor of the floating point equivalent. I'm interested in a method of returning the ceiling instead. For example, ceil(10/5)=2 and ceil(11/5)=3. The obvious approach involves something like:

BVD BVD was founded in 1876 by three gentlemen--Bradley, Voorhees and Day. Together, and with just 3 initials, they created one of the most famous brands in America. BVD may be one of the longest existing brands in the United States garment industry. They originally manufactured both men's and women's undergarments and came to prominence making women's bustiers.

Thread: How to convert CString to char* Re: How to convert CString to char*. Originally Posted by hanhao dont do conversion or casting use CString class to your advantage instead of (LPTSTR)(LPCTSTR)last_line use last_line.GetBuffer(256) instead Depends. CString already has a const char* operator. So if you only need to read the CString's buffer, taking advantage of the const char* operator is easier and safer. Only use GetBuffer if you need to modify the contents, and then only if there isn't an available assignment operator.
