Advantages of c plus plus over java?

Answer 1

The main advantage is that C++ programs compile to native machine code and therefore execute many times faster than equivalent Java programs, which compile to byte code suitable for interpretation by the Java virtual machine. C++ is also more efficient since it requires no interpretation (and therefore no interpreter), and can use memory just as efficiently as assembler. The main disadvantage is the code must be compiled separately for each platform. With Java, programs need only be compiled once for any platform.
