Left shifting an unsigned int by 1 bit is equivalent to multiplying the value by 2. Write a function power2 that takes two integer arguments number and pow and calculates number*(2)^pow Use the shift operator to calculate the result. Print the values as integers and as bits What is the output of this C code? #include 1. void main () 2. {3. int a = 5, b = -7, c = 0, d; 4. d = ++a && ++b || ++c; 5. printf (" % d% d% d% d", a, b, c, d); 6.} a) 6 -6 0 0 b) 6 -5 0 1 c) -6 -6 0 1 d) 6 -6 0 1
