Học thuậtThân thiện
Definition
Noun: A self-contained sequence of instructions within a larger computer program, designed to perform a specific, well-defined task. It is also commonly known as a subroutine, procedure, function, or method, depending on the programming language and context. A subprogram allows for code reuse and modular programming.
Usage
A "subprogram" is called or invoked from other parts of the main program. It typically receives input data (parameters), performs its operations, and may return a result. - The programmer created a subprogram to handle all user input validation. - To calculate the total, the main routine calls a dedicated subprogram. - Debugging is easier when complex logic is isolated in separate subprograms.
Advanced Usage
- Recursive Subprogram: A subprogram that calls itself as part of its execution.
- The factorial calculation was implemented as a recursive subprogram.
- Library Subprogram: A pre-written subprogram stored in a library for common use.
- The math library provides a subprogram for calculating square roots.
Variants and Related Words
- Subroutine: A direct synonym, often used in older or lower-level programming contexts.
- Procedure: A type of subprogram that executes a task but may not return a value.
- Function: A type of subprogram that typically returns a single value.
- Method: A subprogram associated with an object in object-oriented programming.
- Module: A broader term for a collection of related subprograms and data.
