Difference between C & C++

Aspect	C	C++
Paradigm	Procedural programming language	Multi-paradigm language
Abstraction	Basic data types and limited abstraction	Classes, objects, inheritance, polymorphism
Syntax & Features	Simpler syntax with fewer features	Enriched syntax, OOP features, templates
Memory Management	Manual memory management (malloc(), free())	Manual and automatic memory management
Function Overloading	No function overloading	Supports function overloading
Standard Libraries	Limited standard library	Extended standard library
Applications	System-level, embedded, performance-critical	Software dev, games, complex apps
Compatibility	C code can be used in C++ programs	Incorporates C features

C focuses on simplicity and efficiency, while C++ extends support for multiple paradigms and complex software needs.

Difference between C & Java

Aspect	C	Java
Paradigm	Procedural programming language	Object-oriented programming language
Memory Management	Manual memory management (malloc(), free())	Automatic memory management (Garbage Collection)
Platform	Close-to-hardware, platform-dependent	Platform-independent (through Java Virtual Machine)
Syntax & Features	Simple syntax, fewer built-in features	More structured syntax, rich standard library
Pointer Handling	Supports pointers for memory manipulation	No explicit pointers, references used instead
Exception Handling	Basic error handling using return codes	Advanced exception handling mechanism
Compatibility	Limited portability between platforms	High portability due to JVM
Applications	System-level, embedded, performance-critical	Web applications, software development

C is commonly used for system programming and performance-critical applications, while Java is preferred for platform-independent software development, especially web applications.
