Functions and Parameters C++ - Reading Assignment

  1. It is a named area that allows for values external to a function to be passed to a function
  2. So that values external to the function can be supplied to the function

  1. A function parameter is a requirement for a value or set of values to be passed to a function for it to execute. When the function is called, arguments must be provided corresponding with the number of parameters and parameter value types.
  2. Functions need parameters to have access to the values we wish to use. For example,
    int add(){
    return x+y;}
    add(2,2);
    will not make sense to the computer, while
    int add(x,y){
    return x+y;}
    add(2,2);
    does make sense.

  1. Function parameter is a variable that are initiated with a value provided by the caller of the function.
  2. Because sometime you will need to have your value set by the caller to allow your program to perform is task and that the function of base cannot always give access to the value that the user enter.

  1. A variable used in a function where the value is provided by the caller of the function.

  2. Function parameters are needed if you have to pass information to a function to influence its behavior.

  1. What is a function parameter?
    A function parameter is a variable used in a function. They work almost identically to variables defined inside a function, but with the difference that they are always initialized with a value provided by the caller of the function.

  2. Why do functions need parameters?
    Functions need parameters so they can be reuseable by other arguments from a caller function.

A function parameter is a variable that is used in the function. Its value is declared in the caller of that function.

By using parameters, a function can take data as input, perform a manipulation, and return the transformed value.

  1. a variable used in a function
  2. parameters define what the function needs to operate. they differentiate between static variables in the function and dynamic user input variables.

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

1:it’s a variable written in the brackets of the function.

2:they are needed to make interactions between the different functions possible.

Is a variable used in a function. Could be more than 1 value, each one separated by commas and they’re defined between parenthesis after the function identifier.

Because when functions need to interact with the user, they need that information to work with that’s why the caller function passes the arguments(values) to parameters already defined in a function.

  1. What is a function parameter? It is a variable used in a function, they are initialized by a value provided by the caller of the function.
  2. Why do functions need parameters? It lets functions be written in a reusable way without knowing the specific input or outputs are ahead of time.

  1. What is a function parameter?

A function parameter is a variable used in a function.

  1. Why do functions need parameters?

A function needs an input (variable) at the very least to be initiated to produce an output.

  2. Why do functions need parameters?
    A function can take parameters which are simply values that are provided to the function so that the function can do something utilizing those values. They are not necessary for all functions but they do provide an input that can be used or manipulated.

***1. What is a function parameter? A function parameter is a variable that is used in a function.
***2. Why do functions need parameters? Parameters are the source of data that must be used to obtain an output from the function. It is ok if there are no parameters given but then there will be no meaningful output from the function.

  1. a function parameter is a variable used in a function, and they are always initialized with a value provided by the caller of the function.
    they are defined in the function declaration by placing them in between the parenthesis after the function identifier, with multiple parameters being separated by commas.
  2. the number of arguments must generally match the number of function parameters, or the compiler will throw an error. The argument passed to a function can be any valid expression (as the argument is essentially just an initializer for the parameter, and initializers can be any valid expression).
