Answer: - A function in computer science is a block of organized and reusable code that is used to perform a single or related action.

• A function is a block of organized and reusable code that is used to perform a single or related action.
• Functions provide better modularity for our application and a high degree of code for reusing.
• We have already went through the various functions like the printf() and main().
• These are called as the built-in functions provided by the language itself, but we can write our own functions as well.
• The functions are famous with several names.
• Evert different programming languages name the functions differently, for example, the functions, the methods, the sub-routines, the procedures, etc.
• The definition of the function consists of the function header and the function body.

Here are given all the parts of a function: -

1. Return Type: -

• A function might return a value.
• The return type is always the data type of the value that the function will return.
• Some functions perform the desired operations you want without returning the value.
• In this case, the return type is then written as the keyword void.

2. Function Name: -

• This is called as the actual name of the different function.
• The function name and the parameter list all together constitute and is as the function signature.

3. Parameter List: -

• A parameter is like the place holder.
• When a function is invoked, then we will pass a value as a parameter.
• This given value is referred to as the actual parameter or the argument of the function.
• The parameter list refers to the type, order, and the number of the parameters of the given function.
• Parameters are optional, i.e., a function may contain of no parameters.

4. Function Body: -

• The function body contains the collection of the statements that defines what the function does.
