SUBPROGRAMS Meaning and
Definition
-
Subprograms, also known as subroutines or procedures, are self-contained and reusable segments of code within a larger computer program. They are designed to perform specific tasks or functionalities and can be called and executed from different parts of the program whenever needed.
Subprograms essentially break down complex programs into smaller, more manageable parts, helping to improve code organization and maintainability. They promote code reusability by allowing the same set of instructions to be executed multiple times throughout the program, reducing redundancy and enhancing efficiency.
A subprogram is typically defined separately from the main program body and consists of a set of instructions enclosed within a specific syntax or structure. It can optionally have input parameters that are used to pass data to the subprogram, and it may also return output values back to the calling program.
When a subprogram is called, execution flow transfers from the calling program to the subprogram, executes the instructions within it, and then returns to the calling program to continue execution from where it left off.
Subprograms can be thought of as mini-programs or functions within a larger program, each serving a specific purpose. By structuring programs using subprograms, developers can enhance code modularity, readability, and maintainability, ultimately facilitating the development and debugging processes. Subprograms are an important concept in programming languages and are widely used in various programming paradigms, including procedural and object-oriented programming.
Common Misspellings for SUBPROGRAMS
Etymology of SUBPROGRAMS
The term "subprogram" is derived from the combination of two words: "sub" and "program".
The word "sub" is a prefix that means "under" or "below", often denoting something that is subordinate, secondary, or of a lesser scale. It comes from Latin "sub-".
On the other hand, "program" refers to a set of instructions or commands to be executed by a computer or software. It originated from the Latin word "programma", which means "public notice" or "proclamation", and further evolved from Greek "programma" meaning "a written public notice" or "a written document".
Combining these two elements, a "subprogram" in computer science refers to a portion of a larger program that can be executed independently and behaves like a self-contained entity.
