Functions and Parameters C++ - Reading Assignment

[Chris1]

1. function parameter is a variable used in a function - it is always initialized with a value provided by the caller of the function
2. it is useful to be able to pass information to a function being called, so that the function has data to work with - and for that we use parameters in functions.

[Mohamed_Farah]

1. Function parameter is a variable used in the function initialised by the caller of the function.

2. Function parameters are used so that the caller of the function can pass information to the function.

Functions and Parameters C++ - Reading Assignment.

1. A Function parameter is a variable used in a function. It is always initialized with a value provided by the caller.

2. Functions need Parameters because parameters have the values that we want to use in a function. They allow a function to perform tasks without knowing the specific input ahead of time.

1. What is a function parameter?
   A function parameter is a variable used in a function.

2. Why do functions need parameters?
   Parameters are needed in order for the caller to pass data to a function called. The data is then able to be manipulated by the function.

[RikkeHrab]

1. What is a function parameter?
   = Parameters works like variables but inside the function, the caller of the function can via these parameters pass value on to the function.

2. Why do functions need parameters?
   = To make get user specific results from a function.

[jelle_van_der_meer]

1. What is a function parameter?
this is a variable used in a function. The variable is always initialized with the value provided by the caller or the function.

2. Why do functions need parameters?
they need parameters because otherwise they have no value to process. they don’t really need them but otherwise you would just have a dum function that does nothing because it has no parameters.

[jad]

1. What is a function parameter?
It is a variable used in a function. It works almost identically to variables defined inside the function, but with one difference, function parameters are always initiated with a value provided by the caller of the function.

2. Why do functions need parameters?
Functions need data as input, to do some calculation with it.

[William]

1. A function parameter are variables used in a function that are always initialized with a value provided by the caller of the function (ie doubleNumber( int x , int y) <- where the parameter holds the two arguments of int x and int y.

2. Functions need parameters because it allows you to provide information/values to the function, should the function require inputs to execute the code.

[Tyler11]

1. A function parameter is a variable used in a function. They are always initiated with a value provided by the caller of the function.

2. Functions need parameters so they have data to process.

[saf]

1. A variable that is passed to and used by a function.
2. Functions can use parameters as an input that will determine the return value.

[SirGoat]

1. A function parameter is a variables used within a function. It can be information or instructions which are passed to the function.

2. Functions need parameters because the function uses these variables to do something, without parameters it cannot do something!

[Niki_Kou]

1. A function parameter is a variable used in a function.
2. Parameters allow us to pass information or instructions into functions and procedures.

1. What is a function parameter?

A function parameter is a variable used in a function.

Why do functions need parameters?

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.

[RoryPhilBTC]

1. A function parameter is a variable used in a function.

2. This is so that the function has data to work with.

[Eric_Toronto]

1. What is a function parameter?
   A function parameter is a variable used in a function where its initial value is provided by the caller of the function.

2. Why do functions need parameters?
   Parameters allow functions to receive inputs from their caller programs and return outputs that are useful to the caller in the specific context of the latter.

[Julie66]

1. a function parameter is a variable used in a function. It is initialized
   with a value provided by the caller.
2. functions need parameters so that they can be used with different values provided by arguments from the caller.

[kyliezz]

1. A function parameter is a data passed into a function when the function is called.
2. Functions may or may not need parameters to know how exactly to execute the function, depending on the function and data type.

Welcome to the discussion about the reading assignment about Functions and Parameters C++.

Leave your answers to the questions below in this thread. If you have any questions or you want to discuss something connected to the assignment feel free to do it in this thread as well, but please everything to the topic.

1. What is a function parameter?
2. Why do functions need parameters?

1 & 2. A value that is inserted into the function. We create functions that serve their purpose, but we often need to change between the inputs of the function. It is much more efficient, if we only change the input through parameters, than to copy paste the code each time.

[Imhotep]

1. What is a function parameter?
   A function parameter are variables used in a function.

2. Why do functions need parameters?
   To let the user input arguments to initialize the function parameters.

[Jesal_Patel]

1. What is a function parameter?

A variable passed in as an argument to a function after the name within ().

2. Why do functions need parameters?

They may need parameters if the function is to be called by another function and requires it to work with some pre-existing data. If the function reliant on that data is not defined then it may not be able to fulfil its purpose.
