Write a C/C++ program to extract the sign bit, exponent field, and the fraction field of a 32-bit hexadecimal number (in the IEEE 754 standard) and then compute the corresponding floating- point in decimal using the formula (-1)sign ×(1+ fraction ×2-23)×2(exponent-127) (You can ignore special cases including 0). Print each field as unsigned hexadecimal (%X) and the decimal value in scientific notation ("%E"). Then apply for your program to the following four representations (single precision only) 19 ten. -7/6 ten. 0.3 ten. 63.50 ten.
