Java Interview Guide : 200+ Interview Questions and Answers - Differences between C++ and Java

The video discusses the differences between C and Java, focusing on platform independence, object-oriented purity, memory management, and inheritance. Java is platform independent, allowing code to run on any operating system, unlike C. Both languages are not purely object-oriented, but Java is more so due to its restriction on structural programming. C uses pointers for memory access, posing potential security risks, while Java manages memory automatically with garbage collection. Additionally, C supports multiple inheritance, whereas Java does not.
