C is a general-purpose, procedural programming language that was developed by Dennis Ritchie at Bell Laboratories in 1972. 

It is known for its efficiency and flexibility, making it widely used in system programming, application development, and embedded systems. 

C supports structured programming, lexical variable scope, and recursion, and it features a static type system, which helps catch errors at compile time.

Core Java is a subset of the Java programming language that includes the basic features and functionalities necessary for building standard applications. It is primarily associated with Java SE (Java Standard Edition), which provides the foundational APIs and libraries for developing desktop applications, web applications, and more. The principle of Java is "Write Once, Run Anywhere" (WORA), meaning that Java code can run on any platform that has a Java Virtual Machine (JVM) installed

Python is a high-level, general-purpose programming language known for its readability and versatility. Created by Guido van Rossum and first released in 1991, Python has become one of the most popular programming languages worldwide, widely used in various domains such as web development, data science, artificial intelligence, and automation. Python's widespread use in tech giants like Google, Facebook, and Instagram underscores its importance in the software industry.
