left shift

[turboliux]

can someone tell me what is the advantage of using << (left shift) by 1 rather than multyplying by 2? Maybe it had something to do with interpreter?
For example:

code:

int n  = 1; int m = 1; n = n<<1;  //n becomes 2 m = m*2;  //m becomes 2

thnx

bit shifting is faster

It can theoretically be faster. The problem with this is that your compiler may already perform this optimization automatically.

Your best bet is always to say what you mean.
