1.Show the code to set the middle 4 bits of a to 1 (without changing the other bits). Assume a is a char.

2.What is the value (in binary) of b after executing:

b = 0354;

m = 0115;

b = b ^ m;

3.Show the code to copy the middle 4 bits of c to d (without changing the other bits); what is d (in binary) afterwards:

unsigned char c = 0326, d = 0154;
