Final answer:
No, when a function has default arguments for each parameter, you do not need to supply those parameters when calling the function. The function will use the default values provided in the function definition unless overridden by supplied arguments.
Step-by-step explanation:
When you have default arguments for each parameter in a function, you are not required to supply arguments for those parameters when the function is called. This feature of programming languages like Python, C++, Java, and others allows you to write more flexible functions. However, it is worth noting that you can still override the default values by supplying your own values for the parameters when you call the function. If no arguments are provided, the function uses the default values specified in the function definition.
For example, in Python:
def greet(name='World'):
print('Hello, ' + name + '!')
greet() # Outputs: Hello, World!
greet('Alice') # Outputs: Hello, Alice!
In this example, the default argument for name is 'World', but you can provide a different string to greet someone else.
