Clear coding ?

[Henk]

1) I don't like '||' anymore.

Might as well write

if (a) { c }
else if (b) { c }

instead of if (a || b) {c}

Or not ?

Maybe || is shorter but chances are bigger that you overlook a condition.

2) I also don't like 'else'.

So better write

if (a) {c }
if (!a && b) {c }

Don't care about low level efficiency.


3) Eliminating '&&' too. You get:

if (a) {c}
if (!a)
{
if (b) { c}
}

Perhaps step 3 goes too far.

I don't like if(). Instead of

if(x < 0) x = 0;

I always write

x &= -(x >= 0);

Or better yet

x &= ~x>>31;

Of course when you care about readability, you could do

Code: Select all

#define CLIP_OFF_NEGATIVE_PART(x) x &= ~x>>31

CLIP_OFF_NEGATIVE_PART(x);

If I need

if(A) B=C;

I usually write

B = A ? C : B;

I would use 3DES

why dont you use defines:

#define OR ||

if (a OR b) {...}

or

#define OR(a,b) ((a) || (b))

if OR(a,b) {....}

From http://en.cppreference.com/w/cpp/langua ... lternative

In C:

Code: Select all

#include <iso646.h>
if &#40;a or b&#41; &#123; ... &#125;

In C++:

Code: Select all

if (a or b) { ... }

if(x < 0) x = 0;

I always write

x &= -(x >= 0);

Or better yet

x &= ~x>>31;

I usually do this:

Code: Select all

x = max(x, 0);

I use C#.NET which does not have #define.
I thought .NET framework would be beneficial for it contains many classes you can use.


By the way I don't care about '||' but if you have something like
if (a && b && (c || d || e || f))
you might overlook d.

Actually I would like to write fool proof code as much as possible without adding extra complexity.

And this goes right to the pile of evidence that Henk is a troll.
