solve in c++

Using any of the three loops (for, while or do-while), write a program that will evaluate the function y = 4x2 - 16x + 15, with x going from 1 to 2 in steps of 0.1, For each X, give the value of y and the message POSTIVE or NOT POSITIVE as shown here: X value Y value Sign 3.00 1.0 1.1 POSITIVE POSITIVE 2.24 2.0 -1.00 NOT POSITIVE
