Using the C datatype

typedef unsigned int bit32;

and the print function

int printhex(bit32 x){

printf("%.8x", x)}

a) Write a C function to extract the sign, exponent, and fraction of a bit32 floating point number, returning their respective values and unsigned integers.

b) Write a function, float_32(unsigned int sign, unsigned int exp, unsigned in frac) that returns a bit32 representation of a number given a sign, exponent, and fraction vales as unsigned integers.

c) Using the functions defined in (a) and (b), write a function fp_add(bit32 x, bit32 y) that returns the addition of two bit32 values x and y as a floating point bit32 value
