c program usind bitwise operators

[Harika]

Hi all

Any one of you would give me small c program using bitwise operators to below given statement.

A function setbits(x,p,n,y) that returns x with the n bits that begin at position p set to the rightmost n bits of an unsigned char variable y (leaving other bits unchanged).

For ex:

if x = 10101010 (170 decimal) and y = 10100111 (167 decimal) and n = 3 and p = 6 say then you need to strip off 3 bits of y (111) and put them in x at position 10xxx010 to get answer 10111010.

Your output should be like this:

x = 10101010 (binary)
y = 10100111 (binary)
setbits n = 3, p = 6 gives x = 10111010 (binary)

Reply soon as early as possible if you know.

Thank you.

Better to attempt it first and then post if you have problems with writing code.
