What is the difference between arguments and parameters

The procedure's declaration defines its parameters. When you define a Function or Sub procedure, you specify a parameter list in parentheses immediately following the procedure name.

For each parameter, you specify a name, a data type, and a passing mechanism ByVal or ByRef. You can also indicate that a parameter is optional. This means that the calling code does not have to pass a value for it. The name of each parameter serves as a local variable in the procedure.

You use the parameter name the same way you use any other variable. An argument represents the value that you pass to a procedure parameter when you call the procedure. The calling code supplies the arguments when it calls the procedure.

When you call a Function or Sub procedure, you include an argument list in parentheses immediately following the procedure name. Each argument corresponds to the parameter in the same position in the list.

Consider the following program to understand the difference between a parameter and an argument. Now, you want to call this function inside the main function with two different values to add.

The values that you pass during the function call are called arguments to the function. In the above example, we can clearly see the difference between the parameters and arguments.

Default Arguments: These are the arguments that are assigned to the parameters at the time of function definition. Keyword Arguments: These arguments are passed by specifying keywords or names. Since keywords are passed align with the argument values, the order of the arguments does not matter. Arbitrary Arguments: As the name suggests, a function accepting arbitrary arguments can accept any number of arguments. Data Science. Data Science All Courses M.
