Difference between Program and Function Last Updated : 15 Dec, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report 1. Program : Program, as name suggest, are set or collection of instructions used by computer to execute specific task and these are created using particular programming languages such as C++, Python, Ruby, etc. 2. Function : Function, as name suggests, is basic concept in computer programming that one calls to control flow of program as well as perform a specific task, returns a value and resumes program where it was called. Difference between Program and Function : Program Function Programs are set of instructions executed by computer. Function is block of organized and reusable code. Programs has to instruct computer to do particular task. Functions has to perform action or related action. Programs do not return any result. Function usually return result that can be graphed or entered in table. It provides framework that set direction of program as well as plan about how objective will be achieved. It provides better modularity for application as well as high degree of reusing code. It cannot store local and global variables. It can store local and global variables. Types of programs include system programs, application programs, utility programs, etc. Types of function include modulus function, linear function, quadratic function, exponential function, etc. Program consists of compiled code that run directly from computers operating system. Functions can be used over and over again once it is defined. It is larger in size and does not require scripting engine to run. Functions are smaller in size as compared to programs. Programs are written in both low-level and high-level programming languages and are human readable and writable. Functions can be both low-level or top-level functions.

SDLC, or software development life cycle, is a methodology that defines the entire procedure of software development step-by-step. The goal of the SDLC life cycle model is 11 min read Decorators in Python In Python, decorators are a powerful and flexible way to modify or extend the behavior of functions or methods, without changing their actual code. A decorator is essentially a function that takes another function as an argument and returns a new function with enhanced functionality.

Neural networks are machine learning models that mimic the complex functions of the human brain. These models consist of interconnected nodes or neurons that process data, learn patterns and enable tasks such as pattern recognition and decision-making.In this article, we will explore the fundamental 12 min read Difference between BFS and DFS Breadth-First Search (BFS) and Depth-First Search (DFS) are two fundamental algorithms used for traversing or searching graphs and trees.

Data Flow Diagram is a visual representation of the flow of data within the system. It help to understand the flow of data throughout the system, from input to output, and how it gets transformed along the way.
