What's causing 'argumenterror: wrong number of arguments' in ruby?

This error arises when a method call has too few or too many arguments compared to its definition.

Example:

def greet(name)
  puts "Hello, #{name}"
end
greet()

Solution:

def greet(name)
  puts "Hello, #{name}"
end
greet("John")

Ensure that the number of arguments in the method call matches its definition.
