本文介绍了`F（无效）`这意味着在C ++ 11或C没有paramters？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在C ++ 11下面的函数声明：
INT F（无效）;
意思是一样的：
INT F（）;
I get the (perhaps false) impression this is an old feature, perhaps inherited from C?
Does anyone know the history or rationale behind this way to declare a function with no parameters?
解决方案
In C++ they both mean the same thing.
In C f(void) is different from f(), becuse f() means "unspecified parameters" - you can legally pass anything (whether the function at receiving the data is happy about that or not is another matter).
