How do you set, clear and toggle a single bit in C?

Can some one help me how to toggle a bit at ith position. One way is to ((n>>i)^1) < < i. Are there any other ways ?

n ^= 1U << i is easy enough, isn't it?

You could do

pow(2, i) ^ n

you'd have to cast the (inexact) result of pow to an int for that to work. – Mark Elliot Sep 10 '10 at 1:15
    
No, you couldn't. pow returns a double, which is not a valid argument to the ^ operator. There's also no guarantee that pow will give an exact result. – Stephen Canon Sep 10 '10 at 1:16
