(1) When defining an expression with a macro, use complete parentheses. Example: A macro defined below has some risk.#define Rectangle_area (A, b) A * b#define Rectangle_area (A, B) (A * b)#define Rectangle_area (A, B) (a) * (b)The correct definition should be:#define Rectangle_area (A, B) ((a) * (b))(2) Place multiple expressions defined by a macro in curly braces. Example: The following statement is only executed for the first expression of the macro. To illustrate the problem, the For stateme

certain input values of the record, and the other information to respond to different values. In this case, you can use conditions to control the macro process. The condition is a logical expression. Macros are executed along different paths based on the true or false condition results. If this condition is true, Microsoft Access performs the operation in this row. Enter the ellipsis (…) in the condition column of the operation that follows this oper

Common predefined macrosAll compilers that follow the iso c Standard must define the following macros. The macro names start with two underscores and end with two underscores.1. _ DATE __"Alternative text" is a string literal with a compilation date in the format of "mm dd yyyy" (for example, "Mar 19 2006 "). If the date is less than 10 days, place a space character in front of the day.2. _ FILE __The literal value of this string contains the name of

Posture for optionsWhat if there is an "option variable" to represent one or more values at the same time swollen? Then we have to ns_options.For example, there is a simple example:objective-c 12345 typedef ns_options(nsuinteger, jzzpersontype) { jzzpersontypehigh = 0, jzzpersontyperich = 1 0, jzzpersontypepretty = 1 1 }; As you can see, our options here are defined in the way of bitwise operations , and the benefit is that our option variables can be repr

In Unity's cross-platform, we often roam across platforms, such as Android, Apple, andpc. On different platforms, we have to do different things. However, we can use Unity's own macro definition to make platform judgments. Unity helps us define, for example, the following platform preprocessing. (There are also macro definitions of version numbers, which are not written here.) ) We use #if #elif #endif进行宏命令的判断,unity determines which conditions are true and then executes the specified code.

of the member member.2.const typeof (((type *) 0)->member) *__mptr = (PTR) defines the variable __mptr pointer and assigns PTR to __mptr. After this step, __mptr is a constant pointer to the member data type, which points to the address that PTR points to.3. (char *) __MPTR converts the __mptr to a byte-type pointer.4. Offsetof (Type,member)) is to get the position offset of "member member" in "struct type".5. (char *) __mptr-offsetof (Type,member)) is the starting address (a char * type pointe

At the same time Match.call () can get the entire function call syntax tree. If we modify the syntax tree of a function call to accomplish something else, it is actually the function of "macro". One place that differs from Lisp is that we don't need to differentiate between the valuations phase (evaluate pha

Because macros are executed when the control occurs, we need to create the object and then let its corresponding event point to a macro. Create a form to add a button above (If the Button Wizard dialog box appears, click Cancel). Select the event in the Properties window/Click the Builder button to the right, select Macro Builder, and then give the macro a name, such as Macro 1. Select "OpenForm" in the Action column and "Form 1" in t

In PowerPoint, we can also record macros to help us automate a series of actions. 1, the implementation of the "tools → macro → record new macro" command, open the "Record New Macro" dialog box, enter a name, press the "OK" button to record. 2, according to your needs, will be recorded in the process of operation, and then press the "Stop Recording" button, exit the recording status. 3, the implementation of "tools → macro → macro" command, open th
