[algogeeks] Re: switch vs if --> which is faster

[shiva]

how it going to make difference in following case
------------------------------------------
i=0;
switch(i)
{
case 1: //some operation
case 0:// some operation
}
------------------------------------------
i=0;
if(i==1)
{
//some operation;
}
else if (i==0)
{
//Some operation
}
------------------------------------------
even compiler implement jump table like below

key address
1     xxxxx
0     yyyyy

Then two condition (worst case) need to be checked which is same as if
else if

Please correct me if i am wrong
