• Write and execute a program which prompts for and reads a number x, calculates y according to the rule y = 4/3 x for positive x, and y = -0.5 x for negative x. It prints out to the screen x and y with labels, and in addition prints the result to a file called valuespos.txt if x>0 but to a file valuesneg.txt if x <0. ( no need to submit this work).
