Which number?
Here is a numerical expression in C: x c« 1 containing an unknown number z. If the value of the whole expression ( x « 1 )is 42, what
is the value of z?
Here are a couple of numerical expressions in C: x X 5 and x /5 containing an unknown number r. If the value of the expression first
expression is 4 and the value of the second is 3, what is the value of z?
Here are a couple of numerical expression in C: x & 25 and x | 25
29, what is the numerical value of this expression?
If the value of the first expression is 17 and the value of the second is
Lay out the bit patterns of 25, 17 and 29. Consider the bitwise OR first: this will fixall but three of the bits of z. Considering the bitwise AND will
fix the remaining three.
