What is a null macro what is the difference between a null pointer and a null macro?
NULL Macro is simply what is defined as 0 in a macro provided by the libraryNull pointer is a pointer which has 0 or NULL value stored and points to nowhwere still it points to 0x00 i.e. the first memory location of the OSNull pointer != Uninitialized pointer because an uninitialised pointer can point anywhere in the memory location ...but a NULL pointer surely points to no where(but still behind the scene we can say that it only points to 0x00). Never we can retrive a Null pointer location using th"&" operator..neither will malloc/calloc return NULL IF THERE IS SPACE IN THE MEMORY. NULL pointer is unique !!nishantnitb@aol.com
What is the difference between a null pointer and a null macro?
Using a NULL macro to make C portableI'll assume that you're asking your question for C type language programming. A NULL pointer is a pointer that's guarnteed to point to nothing. This may be 0 in a UNIX/Linux system or some other address in another system. Using the NULL macro to set/initialize your pointers will make your programs more portable among systems than using something like the 0.#include char *c = 0; // initialize to NULL--not portablechar *p = NULL; // initialize to NULL as defined in stdio is portableAddendumThe code:char *c = 0;actually is portable because the compiler converts 0's used in a pointer context (cast to a pointer) to the machine's representation of a NULL pointer, which may or may not be all 0 bits. The NULL macro itself might be defined as something like 0 or (void *)0, and both definitions are portable. As a corollary, the following code is also portable:if (!c) {// do something}because it is equivalent to:if (c != 0) {// do something}and the 0 above is converted to a NULL pointer because it is being compared with a pointer.
What is null macro?
The NULL macro is an implementation-defined macro. It is used to symbolise the zero address (0x0) in C programs and older C++ programs. It is not type safe, but is the conventional method of assigning the zero address to a pointer variable. C++11 introduced the type-safe nullptr data type.
Create a macro and assign Ctrl plus l key to run this macro method?
You can record a macro and before starting the recording you can use i key as assigned key to run the macro. Also, if you have an existing macro to which you want to assign i key then Press Alt + F8 which will show you the list of existing macro. Click on Edit and type the i in the assign key box. Remember Ctrl is my default. So, if you want the macro to have Ctrl SHIFT I then turn on the caplock. Your question is not very decriptive in nature.
What is the difference between Typedef and Reference in C plus plus?
A typedef is a compiler macro. A reference is a pointer, usually implemented with transparent syntax. They have no relationship between each other.

What word can be used to duplicate an action to perform again in word document?
The term is 'MACRO.' A macro is a recording of keystrokes that can be played back upon a command. If I type d d a t e without spaces, I get: May 15, 2010 which is today's date.

What is macro call?
Nested macro calls refer to the macro calls within the macros. A macros is available within other macro definitions also. In the scenario when a macro call occurs, which contains another macro call, the macro processor generates the nested macro definition as text and places it on the input stack. The definition of the macro is then scanned and the macro processor complies it.

How do you create macro?
You can create a macro (macro: An action or a set of actions that you can use to automate tasks. Macros are recorded in the Visual Basic for Applications programming language.) by using the macro recorder to record a sequence of actions, or you can create a macro from scratch by entering Visual Basic for Applications (Visual Basic for Applications (VBA): A macro-language version of Microsoft Visual Basic that is used to program Microsoft Windows-based applications and is included with several Microsoft programs.) code in the Visual Basic Editor (Visual Basic Editor: An environment in which you write new and edit existing Visual Basic for Applications code and procedures. The Visual Basic Editor contains a complete debugging toolset for finding syntax, run-time, and logic problems in your code.).You can also use both methods. You can record some steps and then enhance them with additional code.By recording stepsOn the Tools menu, point to Macro, and then click Record New Macro.In the Macro name box, type a name for the macro.In the Store macro in box, click the template (template: A file or files that contain the structure and tools for shaping such elements as the style and page layout of finished files. For example, Word templates can shape a single document, and FrontPage templates can shape an entire Web site.) or document in which you want to store the macro.In the Description box, type a description for the macro.If you don't want to assign the macro to a toolbar (toolbar: A bar with buttons and options that you use to carry out commands. To display a toolbar, press ALT and then SHIFT+F10.), a menu (menu: A list of commands that is displayed when you click a menu name on a menu bar or other toolbar.), or shortcut keys (shortcut key: A function key or key combination, such as F5 or CTRL+A, that you use to carry out a menu command. In contrast, an access key is a key combination, such as ALT+F, that moves the focus to a menu, command, or control.), click OK to begin recording the macro.To assign the macro to a toolbar or menu, click Toolbars, and then click the Commands tab. In the Commands box, click the macro you are recording, and drag it to the toolbar or menu you want to assign it to. Click Close to begin recording the macro.To assign the macro to shortcut keys, click Keyboard. In the Commands box, click the macro you are recording. In the Press new shortcut key box, type the key sequence, and then click Assign. Click Close to begin recording the macro.Perform the actions you want to include in your macro.When you record a macro, you can use the mouse to click commands and options, but not to select text. You must use the keyboard to record these actions. For example, you can use F8 to select text and press END to move the cursor to the end of the line.To stop recording your macro, click Stop Recording.By using Visual Basic for ApplicationsOn the Tools menu, point to Macro, and then click Macros.In the Macros in list, click the template (template: A file or files that contain the structure and tools for shaping such elements as the style and page layout of finished files. For example, Word templates can shape a single document, and FrontPage templates can shape an entire Web site.) or document in which you want to store the macro.In the Macro name box, type a name for the macro.Click Create to open the Visual Basic Editor.Note If you give a new macro the same name as an existing built-in command in Microsoft Word, the new macro actions will replace the existing actions. To view a list of built-in macros in Word, point to Macro on the Tools menu, and then click Macros. In the Macros in list, click Word Commands.
