Question 3: Write a "standard" macro min, this macro enters two parameters and returns the smaller one. Also, what happens when you write the following code. least = MIN (*p++, b); Answer: #define MIN (A,b) ((A) MIN (*p++, b) can create side effects of macros Analysis: This question mainly examines the interviewer's use of the macro definition, a macro definition can implement functions similar to a function, but it is not a function at all, and

Program Jason Clark This article assumes that you are familiar with. NET and C # Download the code for this article: Plug-ins.exe (135KB) Overview Most user applications benefit from the ability to be extended by other developers. Extending an existing application that a user is already familiar with and training for is often simpler and more effective than developing from scratch. Therefore, scalability makes your application more appealing. You can make your application extensible by suppor

In the new Office 2013 version, because of battery life and machine reliability, the removal of features such as macros, Third-party add-ons, and VBA will replace them with a new "cloud app model", a link between Microsoft and developers, and marketing/sales/ Deployment and other software aggregation. Developers have 80% of the gains from the platform, of which 20% are owned by Microsoft. The new version of Office is able to use the web as a workarou

You cannot use SQL expressions in the Criteria column of a macro. Typically, the direct execution of a macro is just a test. You can either attach a macro to a form, report, or control to respond to an event, or create a custom menu command that executes a macro, after you make sure that the macro is designed correctly. If you want Microsoft Access to temporarily ignore an action, enter False as a condition. Temporarily ignoring the action helps you find the problem in the macro. If you want

.3) loop statements and switch results are not allowed in inline functions. Functions with abnormal interface declarations cannot be declared as inline functions.Let's talk about the differences between macros and functions:1. macros are used to replace simple strings (note that the replacement of strings is not the replacement of other types of parameters), while function parameters are transmitted with da

0.#define MALLOC (n, type) \sizeof(type))1. Macros can be defined like functions, such as:#define MIN (x, y) (xBut in the actual use, only when writing min (), must be parentheses, Min will be as a macro expansion, otherwise do not do any processing.2. If the macro requires parameters, you can not pass, the compiler will give you a warning (macro parameters are not enough), but this will result in an error. As depicted in C + + books, the compiler (pr

You can use the macro recorder to record a series of actions to create Macros macro: An action or a set of actions that you can perform to automate tasks. You can record macros in the Visual Basic for Applications programming language. Or in the Visual Basic Editor Visual Basic Editor: An environment for writing new Visual basic for Applications code and procedures, and editing existing code and procedures.

Excel macros are powerful, but are disabled by default because of security risks, and the following small series teaches you how to turn on macro features that are disabled by default in Excel. Excel macros have been disabled for workaround: Click Office buttons, and then click Excel Options, and then click Trust Center, Trust Center settings, and macro settings. Click the option that you want "Disable

I. MAIN objectives(because Visual Studio typically contains many development environments, it is commonly referred to as Visual C + + 20xx)Organize the predefined macros under Visual C + + 2010.

Macros: macro, preset text substitution mode:A macro is an abstract concept (abstraction) that replaces certain text patterns based on some of the predefined rules of a column, whereas an explanation or compiler automatically replaces this pattern when it encounters a macro. Similarly, Zabbix saves the preset text pattern based on a macro, and replaces it with the text in it when it is called.The built-in {MACRO} does not need to be added $ to referen

->member) *__mptr = (PTR);" means declaring a pointer constant *__mptr the same type as member, and initializing it to PTR. "(Type *) ((char *) __mptr-offsetof (type,member))," means that the address of the __mptr is subtracted from the offset of member in the struct and converted to a type pointer. In fact, the pointer is the entry address of member. Here is a new example of my previous online example, which I hope will help the reader:#include /* * The CONTAINER_OF and Offsetof
