C Program to Find the Roots of a Quadratic Equation
This is the example of c-programming. You can edit and compile code in your own way on clicking button. If you have better solution or you found any error on code, then give us suggestion.
Code Explanation :
To understand this example, you should have the knowledge of the following C programming topics:
The standard form of a quadratic equation is:
ax<sup>2</sup> + bx + c = 0, where
a, b and c are real numbers and
a != 0
b2-4ac is known as the discriminant of a quadratic equation. It tells the nature of the roots.
- If the discriminant is greater than
0, the roots are real and different.
- If the discriminant is equal to
0, the roots are real and equal.
- If the discriminant is less than
0, the roots are complex and different.
In this program the function of the
sqrt() library is used to find a number's square root.
