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.

This seems like a homework question. What have you already tried?

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.
