Do we need to edit any of the code he gives us?

Or do we just write our own stuff in the space given? i.e. this part

// *******************************************************************
// ** YOU WILL NEED TO COMPLETE THE FOLLOWING SECTION FOR STAGES 1 - 3
// *******************************************************************

It should say somewhere in the spec, but usually andrewt doesn't want you changing his template code unless he says so.

Ragerunner, was referring to COMP1021

Andrew T isn't that nice, what templates I ask, what?!

dcc compiles your program with alot more debug information. If you ever seg fault with gcc its not very helpful. dcc should be able to tell you where your program seg faulted. It also checks for memory problems, like out of bounds indices.

Basically, it your program ever behaves strangely when compiled with gcc, its probably a memory problem, use dcc instead.

does -pedantic even exist in dcc? i thought its only -Wall and -O etc

im gonna try it, it might give me some insight (ommmmm)

I assure you it exists ...

I think apparently there is a verbose mode also, like DCC isn't verbose enough

 

[ace]

Might as well use Valgrind

if dcc does all that, why even use gcc at all?

i remember having some segmentation faults in a lab using gcc which didnt give me a reason why, or where... so it took ages to debug...

is there any advantage of using gcc over dcc?

Don't use gcc.

In your final build use gcc. Programs compiled using dcc have a lot more debug information compiled into the program. Even with -O3 on, a dcc compiled program is much slower than a gcc compiled program.

No. Except all *NIX will have gcc, not everything has dcc.
