Variable declarations

[jrohde]

Hello all,

Any gain in performance by declaring multiple variables on the same line, or does the compiler treat them exactly the same?

e.g.:

int x, y, z;

As opposed to:

int x;
int y;
int z;

Just curious... thanks.

Exactly the same. And I woudn't worry about performance to much in this sort of matters. When encrypting files with millions of lines, or generating explosions on the screen, performance is important, but in this sort of stuff it doesnt make any (noticalbe) difference.

Compiler would likely generate the exact same code. But that would also be dependent on many other factors (Optimisation level etc).

Performance at such a low level is not something you should be concerned with. Optimising algorithms is much more important.

@Scipio: You will find things like generating explosions onscreen, and even some new encryption applications will utilise the GPU as opposed to the CPU. The CPU offers exponentially more performance especially when crunching figures.
