Given real numbers a, b, c. Find the roots of the quadratic equation ax2 + bx + c = 0, otherwise the answer is to say that there are no roots.

Given real numbers x, y, z. Find out if there is a triangle with sides x, y, z.

Three real numbers are given. To square those of them whose values ​​are nonnegative.

The program asks the user “How old are you?”. You enter a positive number to 100. The program should give a complete answer to "You X (or years or years or year).

The first one is a simple matter of using code to evaluate,

  x = (-b +/- sqrt(b * b - 4 * a * c) ) / 2 * a

The second one can take advantage of a basic property:

if any one side is greater than or equal to the sum of 
the other two, x, y, z are not sides of a triangle.

The others are child’s play.
