2.32 lab: musical note frequencies on a piano, a key has a frequency, say f0. each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). given an initial key frequency, output that frequency and the next 4 higher key frequencies. output each floating-point value with two digits after the decimal point, which can be achieved by executing cout < < fixed < < setprecision(2); once before all other cout statements. ex: if the input is: 440.0 (which is the a key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37
