   A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.

   Why are C functions important?

   • We can call the C Functions many times. So there will be no need to write the same code again and again. C Functions help in the optimization of the C Program because we don’t need to write much code. Declaration of C Function, tells the compiler about a function’s name, it’s the return type and the parameters.

   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:

   What is the syntax for defining a function in C?

   • The following is the syntax for defining a function in C: Here, return_type is the data type of the value that the function returns. function_name is the name of the function, and parameter_list is the list of parameters that the function takes as input.

   How to create a function in C?

   • A function in C can be created using this syntax: The return_type specifies the type of value that the function will return. If the function does not return anything, the return_type will be void. The function_name is the name of the function, and the parameter list specifies the parameters that the function will take in.

   Where can a function be defined in C?

   • In C, a function can be defined anywhere in the program, as long as it is defined before it is used. But it is a good practice to define functions at the beginning of the file or in a separate file to make the code more readable and organized.

   What is a function implementation?

   • The function implementation is defined in a separate file math.c. This approach allows for better code organization and modularity, as the function implementation can be separated from the main program code. We can call a function from anywhere in the program once we've defined it.
