programming get start 一問

To write a program, you only need to use Notepad included in Windows,
or any other text editor
to write the source of the program. After that, you need to use a
compiler to convert your source into an executable file. This compiler
needs to be downloaded from the Internet. Different computer language
use different compilers. For example, you need to download JDK
from Sun in order to make Java program.

There are many many books that teach you how to write programs
For a 14 years old guy like you, I don't think that learning Java/C++
is a good start. Visual Basic may be more appropriate for you.
If you insist on it, I suggest you looking for some
fundamental programming book, such as "How to program in C++"
and "How to program in Java". These are very good books for beginners
and even for advanced programmers.

Hope this helps.
