Set sixth bit to 1

Given a sixteen bit number. How can sixth bit can be set to 1 irrespective of its initial value and sixth bit reset to zero irrespective of its initial value

suppose 'a' contains 16 bit number. And initialize b with 32.

a=a|b; /*this will convert 6th bit to One irrespective of its original bit*/

now for making 6th bit 0, load b with 65503 and do the following.
a=a&b;

for setting the 6th bit:
x | (1<<5)

for unsetting the 6th bit:
x & (~(1<<5))

hope it helps.

You could also use the OR and AND operators to help you put.

#define MASK1 0x0040 // Note that 6th bit is 1, counting from 0
#define MASK2 0xffbf // Note that the 6th bit is 0

// Set 6th bit of x to 1
x = x | MASK1

// Set 6th bit of x to 0
x = x & MASK2

what the hell is the answr..
