Question

What are the two types of parameters in programming?

Answer 1

In programming, there are two main types of parameters:

1. Formal Parameters:
   

   - These are the parameters that are defined in the function or method declaration.
   - They act as placeholders that specify what kind of values the function expects to receive when called.
   - Example:
     `python
     def greet(name):  # 'name' is a formal parameter
         print(f"Hello, {name}!")
     `

1. Actual (or Argument) Parameters:
   

   - These are the real values or data that are passed to the function when it is called.
   - These values are given to the function in place of the formal parameters.
   - Example:
     `python
     greet("Alice")  # "Alice" is an actual parameter
     `

So, in simple terms, formal parameters are what you define in the function, and actual parameters are what you pass when you call the function.
