When creating userdefined functions we can pass parameters into the function definition to be used in some way with those executable commands. We can also return values from the function definition back to the function call. This is one way we can address the variable scope restriction in any one function.

FunctionPrototypeincpng

When defining the function\'s prototype, the data type before the function name represents the data type of the value being returned from the function call. The datatype and sometimes variable name inside of the parentheses after the function name represent the value being passed from the function call into the definition. Keep in mind that the void keyword is representative of no values being passed or returned.

For this exercise, you will be creating a function that passes a value the year into the function definition and then the function definition will make decisions to see if that year is a leap year. A value will be returned to the function call based on whether the year is a leap year or not. Be sure to pay attention to the function prototype and how it differs from the previous exercise.
