    What do the (x=1) && (y=10) and (x=1) & (y=10) expressions return, respectively?
    Given x = 96, y = 1, and z = 69, what does the expression !y ? x == z : y return?
    What do the ~0011000000111001 and ~1100111111000110 expressions return?
    Given x=9, what does (x%2==0)||(x%3==0) return? How about (x%2==0)&&(x%3==0)?
    Is 8 >> 3 equivalent to 8 / 23? How about 1 << 3?


    Given x = 0xEFFF and y = 0x1000, what do ~x and ~y return, respectively, in the hex format?
    Taking the values of x and y assigned in exercise 1, write a program that prints out the return values of !x and !y by using both the %d and %u formats in the printf() function.

    Given x = 123 and y = 4, write a program that displays the results of the x << y and x >> y expressions.
    Write a program that shows the return values (in hex) of the 0xFFFF^0x8888, 0xABCD & 0x4567, and 0xDCBA | 0x1234 expressions.
    Use the ?: operator and the for statement to write a program that keeps taking the characters entered by the user until the character q is accounted. (Hint: Put the x!='q' ? 1 : 0 expression to the second field in the for statement.)
