I'll try to explain with an example... Let's say I have two different functions, and one of them has a defined variable. In the second function, I don't wanna write the same variable again, can I simply use the variable from the first function in the second one WITHOUT redefining it in the second function? Something like: function a()...

While debugging some C code with gdb I came across something I've not seen nor heard of before! The compiler (gcc -O0) seems to have created a new type for passing an array of vectors to a function... I think! Have a look at the code and gdb information below: /* The Vector type - nothing unusual */ typedef struct { float x,y,z; } V...

I've created a variable length array in one function, however I need to refer to this array in a second function. The problem occurs when I put the declaration above main() seeing as its length hasn't been defined yet, my compiler gets angry. How does one typically go about this? EDIT: Here is my code so far. I need to make the ar...

We have a JQuery $(function() statement as: <script type="text/javascript"> $(function(){ //Code.. }) </script> Dumb question - when exactly is this function executed? Is it when the entire HTML page has been downloaded by the client? What is benefit of using the wrapping your code within $(function() as opposed to just doing: ...
We have an HTML page with some global JavaScript variables. We have some utility functions that manipulate these variables. Can you move these util functions to a separate JavaScript file and include the file using the <script> tag? Wasn't sure if the functions in the external file could get/set the global variables that are defined i...
