What are Macros?

[beingchinmay]

Macros are preprocessor, it’s unique feature of C language. Preprocessor improves the readability of the program and hence the developed code is more efficient. Preprocessor directives consist of three sub categories

•Macro substitution division
•Complier control division
•File inclusion division

A macro is a shortcut to a task you do repeatedly. Think about the Centre align operation.

 

[andrea992]

Whenever the name is used, it is replaced by the contents of the macro. ... Object-like macros resemble data objects when used, function-like macros resemble function calls. You may define any valid identifier as a macro, even if it is a C keyword. The preprocessor does not know anything about keywords.

macrois a single instruction that expands automatically into a set of instructions to perform a particular task.

A special-purpose command language used to automate sequences within an application such as a spreadsheet or word processor. Macro languages often include programming controls (IF THEN, GOTO, WHILE, etc.), but rarely have the capabilities of a full-blown programming language. See macro recorder, batch file and shell script.

It is a name given to the block of C statements as a pre-processor directive. And it is defined with the Pre-processor directive, #define.

n Microsoft Word and other programs, a macro is a saved sequence of command s or keyboard strokes that can be stored and then recalled with a single command or keyboard stroke.

 

[Cory Huffman]

In computers, a macro (for "large"; the opposite of "micro") is any programming or user interface that, when used, expands into something larger. The original use for "macro" or "macro definition" was in computer assembler language before higher-level, easier-to-code languages became more common.
