The difference between Java and c++,c and C + +

Let's start by analyzing the differences between Java and C + +:

Java is a purely object-oriented language, and C + + is a language based on object-oriented procedures.

Java has a garbage collection mechanism. Its syntax is a subset of C + +, which has C + + in Java. and C + + Some Java does not have all.

Java also includes built-in types and their own definition types. In the local open space, after the ability to use the value. The types of Java are treated as objects. No operator. No self-increment action, treat operator as function
Java also has a garbage collection mechanism. Reflection mechanism.

Then analyze C and C + + differences:

C has only member variables, there is no way to say, and C + + has its own member variables and member functions;

The latter has references to function overloads. Template (code at compile time), operator overloading.

The latter function has default values. And the former did not.
