Answer:
An argument is a value that is passed to a function or method when it is called. The function or method can then use the argument in its code. The number of arguments that a function or method can take is determined by its definition. Some functions or methods may take no arguments, while others may take one or more.
A return value is a value that is returned by a function or method after it has completed its execution. A function or method can have zero or one return value. In some programming languages, a function or method can return multiple values by using an array or some other collection data type.
It is important to note that the terms "argument" and "parameter" are often used interchangeably, but they are not exactly the same thing. A parameter is a variable in the definition of a function or method that represents an argument that will be passed to the function or method when it is called. The argument is the actual value that is passed to the function or method when it is called.
