Let's compare C++, Java, and Python in simple language.
C++ vs. Java:
| Topic | C++ | Java |
| Memory Management | Uses pointers, structures, and unions. | No pointers; uses references, threads, and interfaces. |
| Libraries | Has low-level functionalities. | Offers a wide range of high-level services. |
| Multiple Inheritance | Supports both single and multiple inheritance. | Multiple inheritance through interfaces. |
| Operator Overloading | Supports operator overloading. | Does not support operator overloading. |
| Program Handling | Functions and variables can be outside classes. | Functions and variables are inside classes only. |
| Portability | Platform dependent; needs recompilation for different OS. | Platform independent; byte code works on all OS. |
| Thread Support | No built-in thread support; depends on libraries. | Built-in thread support. |
Java vs. Python:
| Topic | Java | Python |
| Compilation Process | Both compiled and interpreted; compiled to byte code first. | Interpreted language. |
| Code Length | Requires longer code compared to Python. | 3-5 times shorter code than Java. |
| Syntax Complexity | Uses curly braces and semicolons. | No curly braces or semicolons; uses indentation. |
| Ease of Typing | Strongly typed; must define data types for variables. | Dynamically typed; no need to define data types. |
| Speed of Execution | Faster execution speed. | Slower execution speed than Java. |
| Multiple Inheritance | Partially done through interfaces. | Supports both single and multiple inheritance. |
Summary:
C++: Fast and efficient, good for system-level programming.
Java: Platform-independent, good for large applications.
Python: Easy to write and read, good for quick development and prototyping.
