# How to Clear Radio Button Selected Value in C?<\/p>\n

When developing an application or website using C programming language, you may encounter a situation where you need to clear the selected value of a radio button. Whether it is a result of a user action or a programmatic requirement, clearing a radio button’s selected value is a simple task. In this article, we will discuss the approach to clear a radio button selected value in C.<\/p>\n

In C, radio buttons are often implemented as a group of related variables or an array of structures, where each element represents a distinct radio button. To clear the selected value of a radio button, you can simply set the corresponding variable or structure element to its default or null value.<\/p>\n

Let’s assume we have a radio button group called “color” with three options: red, green, and blue. Here’s how you can clear the selection:<\/p>\n

“`c
\n\/\/ Declare variables representing radio button options
\nint red = 0;
\nint green = 0;
\nint blue = 0;
\n“`<\/p>\n

To clear the selection, set all the variables to zero or their default values:<\/p>\n

“`c
\nred = 0;
\ngreen = 0;
\nblue = 0;
\n“`<\/p>\n

This ensures that none of the radio buttons are selected, as their corresponding variables do not have any value representing a selection.<\/p>\n
