Functions and Parameters C++ - Reading Assignment

[cmerced1]

1. a function parameter is a variable used in a function where the value of the parameter is provided by the caller.
2. So reusable statements inside the function can have different values at a given time.

[Lucus]

1. a variable used in a function
2. so the function knows what data is being used and executed.

[RKumovski]

1. These are variables (pre-declared for the function) which values are assigned within the function call.

2. Because every function has a certain “scope” of execution and variables declared/initiated outside of that scope are not “visible” for this function. When such values are required for the proper execution of a function, we pass them to it via parameters.

[Jedi]

1. Function parameters are variables that are defined in the function declaration between parenthesis after the function identifier. These parameters are initialized with arguments passed to the function by a function call.

2. Functions need parameters to define what kind of arguments are acceptable for computation and output.

[Myc]

What is a function parameter? // Function parameters are variables defined inside the function and always initialized with a value provided by the caller of the function.

Why do functions need parameters? //Parameters tell functions which values to use.

[Jun_0113]

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

2. Why do functions need parameters?
   -> To use the parameters in the function.

[Gregorius]

1. A function parameter is a variable used in a function that is initialized with a value provided by the caller of the function.
2. Functions need parameters as a source of data to work with or to specify their behaviour.

[silvrbitcoin]

1.) A function parameter is a variable used in a function. The work similar to variables but with one distinct difference that they are always initialized with a value provided by the caller of the function.
2.) Functions need parameters to give the function a task to execute and to define that task for computational purposes of that function. If a function has no parameters define it cannot execute any task.

[laserkavajen]

What is a function parameter?

It is the variable passed to functions.

Why do functions need parameters?

Without parameters the function decrease it’s utility adding parameters the function increase it’s utility parameters are useful for passing the values of functions so they can perform tasks without those values.

[peros369]

1. A function parameter is a variable used in a function. It is defined inside parenthesis after the function name and are seperated by commas.
2. Functions dont neccesarily need parameters, but there are cases where adding parameters is useful. By including parameters in the function we give function information on which parameters it should use in order to execute the statements that are inside that function.

[CB70]

1. What is a function parameter?
   A function parameter is a variable used in a function. They are always initialised with a value provided by the caller of the function. They are defined in the function declaration, between the (), multiple parameters are separated by commas.
   Example:
   int Add3Numbers (int x,int y, int z)

2. Why do functions need parameters?
   Function parameters are not mandatory, but they are very useful because they allow the function to have meaningful data to work with. The reusable statements within the function can perform computations (tasks) on the specific values assigned to those parameters. The parameter says the same, but the values assigned to them can change.

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

1 a function parameter is a variable used in a function
2 parameters is not mandatory in the code, but it can initialize with a value provided by the caller of the function. this allows it to perform task and return retrieved or calculated results back to the caller without knowing what the specific inputs or outputs are ahead of time to ensure accurate results

[matty.t]

1. A function parameter is a variable used in a function
2. Function parameters and return values are the key mechanisms by which functions can be written in a reusable way, as it allows us to write functions that can perform tasks and return retrieved or calculated results back to the caller without knowing what the specific inputs or outputs are ahead of time.

[Yuanming]

1. A function parameter is a variable that is defined with a value provided by the caller of the function. For example, void print(int x), the integer parameter is x and the caller will supply the value of x.

2. Functions use the parameters to determine the value(s) of the variable(s) within the function. They are not mandatory but are useful for creating functions with variable(s).

[Edwin22]

1. A function parameter is a variable used in a function, always initialized by the caller of the function
2. It is a way of passing values in a function to be used in the function. The function can be called a have different outcomes based on the parameters that are fed into the function

[Fosback]

@ivan

What is a function parameter?

It is a field where you can pass information into the function.

@ivan

Why do functions need parameters?

Without parameters there would be no way of passing information into the function.

[BERGLUND]

1 A variable used in a function, provided by the caller.
2 The parameter(s) is the input to the function, there are functions that do not reqire arguments or parameters.

[sandrau]

1. What is a function parameter? A function parameter is a variable used in a function
2. Why do functions need parameters? Parameters are essential to functions,so you can give the function-machine an input.

[NLUGNER]

Q.)What is a function parameter?
A.)In C++ programming, you can provide default values for function parameters. The idea behind default argument is simple. If a function is called by passing argument/s, those arguments are used by the function. But if the argument/s are not passed while invoking a function then, the default values are used.
Q.) Why do functions need parameters?
A.)Each parameter looks very much like a regular variable declaration (for example: int x ), and in fact acts within the function as a regular variable which is local to the function. The purpose of parameters is to allow passing arguments to the function from the location where it is called from.
