In Appendix A, we discuss the format of short floating-point numbers. Write a program that reads the floating-point internal representation from the user as a string of eight hexadecimal digits and displays the three components—mantissa, exponent, and sign—in binary. For example, if the input to the program is 429DA000, the output should be

 

Suppose you are given an integer that requires 16 bits to store. You are asked to find whether its binary representation has an odd or even number of 1s. Write a program that reads an integer (it should accept both positive and negative numbers) from the user and outputs whether it contains an odd or even number of 1s. Your program should also print the number of 1s in the binary representation.
