# C Program to Find the Roots of a Quadratic Equation

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```

The term `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.

Our example mainly covers following topics in any programing

• Basic Programs
• Number Programs
• Array Programs
• Matrix Programs
• Pattern Programs
• String Programs
• Tree Programs

Here we share programs on various topics such as array strings, series area & volume of geometric figures, mathematical calculation algorithms for sorting & searching and much more.Our goal is to provide you with the perfect solution to all the programming problems you may have encountered either during interviews or in class assignments. If you don’t find what you are looking for then please drop a line in the comment section of example page or you can request from account page so that we can get it added to the below collection of programs. Happy Learning!!

If you are confident with the above programs and are able to successfully understand and run them without any problems then it is time for you to take a step further and learn comprehensive programming principles using examples and flow diagrams. Here is the link: Programming tutorial lists .
