Arguments or parameters?

I got parameter and argument kind of mixed up and did not really pay attention to when to use one and when to use the other.

Can you please tell me?

A parameter is the variable which is part of the method's signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.
