x=x+1 vs. x +=1

Question

I\'m under the impression that these two commands result in the same end, namely incrementing X by 1 but that the latter is probably more efficient.

If this is not c

Answer 1

On x86, if x is in register eax, they will both result in something like

inc eax;

So you're right, after some compilation stage, the IL will be the same.

There's a whole class of questions like this that can be answered with "trust your optimizer."

The famous myth is that
x++;
is less efficient than
++x;
because it has to store a temporary value. If you never use the temporary value, the optimizer will remove that store.
