   What is a function in C programming?

   • A function is a block of code that performs a specific task. Suppose, you need to create a program to create a circle and color it. You can create two functions to solve this problem: Dividing a complex problem into smaller chunks makes our program easy to understand and reuse. There are two types of function in C programming:

   Why are functions important in C?

   • Functions are important because they organize your code and promote code reusability. Instead of writing the same code again and again and repeating yourself, you write code once and then can use it whenever you want to perform that specific task. In C, there are generally two types of functions: Standard library functions.
