SUBPROGRAM Meaning and
Definition
-
A subprogram is a self-contained, independent unit of programming code that is designed to perform a specific task within a larger program. It is also referred to as a subroutine, procedure, function, or method.
A subprogram can be thought of as a mini-program within a larger one. It is created to carry out a particular set of instructions, which can be called and executed whenever needed, rather than repeating the same code multiple times throughout the program. This modular approach promotes code reusability, enhances program organization, and simplifies maintenance and debugging.
Subprograms typically accept input parameters (arguments) and produce output values. They can be defined and implemented separately from the main program or can be embedded within the program's structure. The code within a subprogram is self-contained, meaning it operates independently of the main program, with its own local variables and logical flow.
Subprograms are commonly used to perform common or repetitive tasks, or to break down complex operations into smaller, manageable parts. They can be used across different sections of a program or even across multiple programs. By encapsulating specific functionalities, subprograms promote encapsulation, increase code readability, and allow for easier understanding and modification of the overall program.
Overall, a subprogram serves as a building block for software development, providing a modular and reusable way to implement specific functionalities within a program.
Common Misspellings for SUBPROGRAM
Etymology of SUBPROGRAM
The word "subprogram" is derived from the combination of two words: "sub" and "program".
-"Sub" is a prefix derived from Latin, meaning "under" or "below". It is commonly used to indicate something smaller, lesser, or subordinate to something else.
-"Program" comes from the French word "programme" and ultimately from the Latin word "programma", which means "written public notice or proclamation". It refers to a planned sequence of instructions or coding statements to accomplish a specific task in computer science.
Therefore, the term "subprogram" refers to a smaller or subordinate program within a larger program. It is often used to describe a segment of code that performs a specific task and can be called or invoked by other parts of the program, promoting modularity and code reuse.
