A macro is a sequence of computer instructions or commands that are grouped together to automate repetitive tasks and can be executed with a single command or keystroke. It simplifies programming or task execution by expanding a short instruction into a larger set of operations, making work faster and less error-prone.
Macro in Computer Science
In computer programming, a macro is a rule or pattern that specifies how an input should be transformed into an output. It often serves to make a sequence of instructions available as a single statement, facilitating code reuse and automation.
Uses and Benefits
Macros are commonly used to automate repetitive tasks, such as data entry, document formatting, or running a series of commands within an application. They can save time, reduce errors, and increase productivity in software like Microsoft Office.
Macro in Programming Languages
In languages like C, macros are defined using the #define directive and represent constants or code snippets that the compiler replaces during preprocessing.
Other Contexts
In gaming, "macro" can refer to large-scale strategy management (macro gameplay) as opposed to controlling small details (micro gameplay).
In short, a macro is a tool or instruction that automates complex or repetitive processes, making them easier and faster to perform.
