I need help with this question fellas.
Write a function called “QuadRoot”that takes user input for a quadratic function (ax^2+bx+c), a, b and c
and calculates the roots of the function.
Note: if the function does not have any real root, show a message indicating that there
is no real root.

in your code you wrote
d = sqrt(b*b-4*a*c);
and then check if d > 0. This is not the correct condition. You need to check if
d = b*b-4*a*c;
if d > 0
to check if the root is real or not.
