Futter Square Button

To create a button with rounded corners in C, you can use the border-radius property in conjunction with a CSS class. Here's an example:

#include <stdio.h>

int main() {
   printf("<button class=\"rounded-button\">Click me</button>");
   return 0;
}

In this example, we use the printf function to output the HTML code for the button. The class attribute is set to "rounded-button", which you can define in your CSS file to apply the rounded corner styles.
