Write a C-function with two arguments (n and r) that has prototype: char clearbit(char k, char bits) The function clears (sets to 0) the bit number k (in the range of 0 to 7) in bits and returns the resulting value. For example, if k is 0x02 and bits is 0x07, the function would return bits with its k’th bit cleared, resulting in 0x03. It must not change other bits in bits. Hint: You may use any number of C-statements, but this task can be accomplished in as few as one!
