10.11 (Left Shifting Integers ) Left shifting an unsigned int by
1 bit is equivalent to multiplying the value by 2. Write function
power2 that takes two integer arguments number and pow and
calculates number * 2pow. You should declare pow as an unsigned
integer , but remember that the result may be a negative value .
Use the shift operator to calculate the result. Print the values as
integers and as bits . Assume that an integer is of...
Suppose you have 3 N-bit unsigned integers: a, b, and c. What is the minimum number of bits required to present: (a*b)+c in order not to get an overflow? Explain how you reached your answer.
Given n bits, how many unsigned integers can be represented with the n bits? What is the range of these integers? (6 points) There are 26 characters in the alphabet we use for writing English. What is the least number of bits needed to give each character a unique bit pattern? How many bits would we need to distinguish between upper- and lowercase versions of all 26 characters? (12 points)
