Enter tha value of a:2 Enter tha value of b:5 Enter tha value of c:3 First root of quadratic equation=-1.250000 Second root of quadratic equation=-1.250000

It compiles and runs for me. Have you tried a complier updated since you were born?

But you can easily pick values of a, b, and c that would give that error (1, 0, 1 for example). You really need to check that z is not negative; otherwise there are no real solutions to the equation. A good program would solve all cases by producing complex answers too.
