1. What is a function parameter?
A Value or a variable that is passed in to a function so that the function can perform some operation upon it.
2. Why do functions need parameters?
functions are like an operation that is done to data (most of the time) so, naturally you would input data so that has data to perform it’s operation upon then, usually it returns the result.

  1. What is a function parameter?
  • A 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.
    Function parameters are defined in the function declaration by placing them in between the parenthesis
    after the function identifier, with multiple parameters being separated by commas.
  1. Why do functions need parameters?
  • Parameters are essential to functions, because otherwise you can’t give the function-machine an input.

  2. Because it permits to interact and use data from the whole program

1. What is a function parameter?
A variable used in a function. But it’s different from the variable declared inside the function as the function parameter is initialized by the argument in the function call.

2. Why do functions need parameters?
Functions need parameters to store useful information passed by the caller to work upon.

  1. What is a function parameter?

A function parameter is what you give to a function in order for
it to create the appropriate output.

  1. Why do functions need parameters?

Without a parameter, functions will be very limited.

1. What is a function parameter?
A function parameter is a variable used in a function.
2. Why do functions need parameters?
They don`t necessarily need one but, in many cases, it is useful to be able to pass information to a function being called, so that the function has data to work with.

1. What is a function parameter?
A function parameter is a variable that is passed to a function, but the variable is already initialized with a value provided by the function caller.

int add(int x, int y){ //Here, x and y are integer parameters
return x + y;
}

2. Why do functions need parameters?
So functions can modify pre-existing variables without having to recreate them again within the function body.

  1. Function parameter is the variable used in a function. example is void altCoins (int x, int y) { }
    the int x and int y is the parameters.

  2. Parameters are not mandatory. But it allows the caller to initialize the value of the parameter.
