In this program, we declare double variables “a”, “b”, and “c”, which represent the coefficients of the quadratic equation. We prompt the user to enter these values using the “scanf” function. We then calculate the discriminant of the quadratic equation using the formula “b^2 – 4ac”. If the discriminant is greater than 0, it means…
