Freeman IT Services Interview Questions and Answers

Two popular programming languages!

C++ and Java are both high-level, object-oriented programming languages, but they have some key differences:

C++:

- Statically-typed
- Compiled language (faster execution)
- Memory management through pointers (more control, but also more error-prone)
- Performance-oriented
- Widely used for systems programming, game development, and high-performance applications

Java:

- Dynamically-typed
- Interpreted language (slower execution, but easier development)
- Memory management through garbage collection (less control, but fewer memory errors)
- Platform-independent (write once, run anywhere)
- Widely used for web development, Android app development, and enterprise software development

In summary, C++ is a more low-level, performance-focused language, while Java is a higher-level, platform-independent language. The choice between the two often depends on the specific needs of the project.
