  1. to declare the input variable(s) of the function.
  2. when a function needs to process external data, they need parameters.

  1. What is a function parameter?

“A function parameter is a variable used in a function.”

  1. Why do functions need parameters?

To tell the function which values to use

  1. They are variables that require input from the caller.
  2. That way the program knows what we want it to find specifically.

  1. What is a function parameter?
    A function parameter is a variable used in a function. It is defined in the function declaration by placing them in between the parenthesis after the function identifier, with multiple parameters being separated by commas. Important to refer that they are always initialized with a value provided by the caller of the function.

  2. Why do functions need parameters?
    We need these parameters to pass information to a function, letting that function to become reusable.

#147
  1. a variable passed as argument and used in funciton
  2. they not necessarily need them, but if necessary they can work with them
#148
  1. Function parameter is a variable used in a function. Always initialized by the caller of a function.
  2. Function need parameter so it could be written in a reusable way. Also allow us to write functions that can perform tasks and return retrieved or calculated results back to the caller without knowing the specific inputs or outputs ahead of time.

To know the value of a variable the function has inside of, you insert parameter

1 A function parameter is a variable used in a function.
2 Parameters are not mandatory. But it allow you to give information to the function. Then the function can modify variables, work on it…

What is a function parameter? Function parameter is a variable used in a function. Function parameters work almost identically to variables defined inside the function, but with one difference: they are always initialized with a value provided by the caller of the function.
Why do functions need parameters? When a function is called, all of the parameters of the function are created as variables, and the value of each of the arguments is copied into the matching parameter.

1 A variable in a function
2 So the function has input to compute.

  1. What is a function parameter?
  • a variable used in functions
  • almost identical to variables defined inside the function - difference always initialized with a value
  1. Why do functions need parameters?
  • Parameters are in general not needed for functions. But if you´re using them, the parameters give the variables to work with and have to be in the right way.

  1. A function parameter is input that the function needs to do its job.
  2. Functions need parameters to have the information they need to perform the tasks that are requested of them.

  1. What is a function parameter? an empty variable argument declared within the functions brackets, used to perform the instructions within the function body.

  2. Why do functions need parameters? They are not needed, but are used more often than not to provide data to be manipulated.

  1. A function parameter is a variable that you pass into a function because it is necessary for the output.

  2. Some functions need access to data or variables that they would not normally unless they are passed in as parameters

  1. It’s a value that a function takes as input and can use in operations.

  2. In order for data to be passed to the function by the caller.

  1. What is a function parameter?
    it acts as an input value for a function

  2. Why do functions need parameters?
    functions without parameters can be created, so they are not needed, however if you want your function to perform a series of computations on a specific set of data then the parameters need to be created

What is a function parameter?
It is the type and name of a value that is expected to be passed into the called function.

Why do functions need parameters?
It is a means of providing data or values that a function will need to do its work.
