PART A. A bit (pun) more masking. Byte extraction and insertion code is useful in many contexts. Being able to write this sort of code is an important skill to foster. Suppose we number bytes in a 32 bit word from 0 (least significant bits) to 3 (most significant bits). Write code for the following C function, which will return an unsigned value in which byte i of argument * has been replaced by byte b. Complete the main function so that it can be used to test the replace byte function unsigned replace byte (unsigned x, int i, unsigned char b){ *your co below*/ I return ?; } void main{ Il complete the main function here. (use more space if necessary) tttttt
