  1. I find Java daunting.C and C++ not.

  2. Do you understand what "scope" means?

  3. Hexadecimal is a base 16 counting system using 16 symbols.... 0...9 and a...f Example: 1a hexadecimal is equal to 26 in decimal. The advantage is that two hex digits fit into one byte. A 16 bit value would typically be written something like 0xe8b2, where the 0x prefix indicates a hexadecimal number, and the e8b2 equals 59,570 in decimal.

  4. You can do x=y;

  5. Not really. The most common reasons are to prevent the copying of large structures or as a form of pass by reference. There wouldn't be any pointless searching. Everything is available in the compiler's symbol table or in the object files, effectively hard coded. Remember, at the machine level, it's effectivelly all pointers. What you said is more likely to be true of an interpreted language.

  6. The C language does not have pass by reference i.e. &. At least not the last time I checked. That's why pointers are used.

  7. In what way?

  8. Java sucks big time.

  9. I love programming. Been doing it for 30 years. Once you understand the concepts it will be easy.

  10. A memory address with some type information.

  11. C++ is a normal language. It's probably the most widely used language of the past 40 years.
