This example prints2to standard output, because theareferred to in the declaration ofg()is the one at file scope, which has the value2wheng()is called. The default argument must be implicitly convertible to the parameter type. A pointer to a function must have the same type as the functi...

In this case, display() uses both the default parameters c = '*' and n = 1. display('#') is called with only one argument. In this case, the first becomes '#'. The second default parameter n = 1 is retained. display('#', count) is called with both arguments. In this case,...
In many cases, functions have arguments that are used so infrequently that a default value would suffice. To address this, the default-argument facility allows for specifying only those arguments to a function that are meaningful in a given call. To illustrate this concept, consider the example ...
If the caller provides an argument, the value of the argument in the function call is used. If the caller does not provide an argument, the value of the default argument is used. Consider the following program: #include <iostream> void print(int x, int y=4) // 4 is the default ...
I've found over the years that the meaning of true or false is so easily lost, and so easily forgotten which is the "without argument" state that I've gone to using an Enum that clearly described the behavior. Years later: var tweets = TweetRepo.GetLatestTweets(tweepId, DirtyWords....

It would probably make more sense to have the returned function be the one that takes the default, but in that case you might as well just use getattr. If we did accept a keyword-only argument for a default, what does the default mean if there is more than one key? And what if ...
C Cottarelli,P Mauro,L Forni,J Gottschalk 摘要: This note summarizes the main arguments put forward by some market commentators who argue that default is inevitable, and presents a rebuttal for each argument in turn. Their main arguments focus on the size of the adjustment and continued ...
