How to find sqrt roots of an quadratic equation in c++

Question

Answer 1

You can use the function sqrt() defined in the <cmath> header file to compute square roots.
Just include the header in your program to use it.

On the other hand, you could make your own function. Here is an example on how to do that (not my own though):
