The default returns value from a function in int. In other words generally unless explicitly specified the default return value by compiler would be integer value from function. So when a programmer wants other than integer values to be returned from function then it is essential that the ...
int (*badpointer)() = &f; // error, badpointer and f have // different types. badpointer must // be initialized with a pointer to // a function taking no arguments. In this example, functionf3has a return typeint, and takes anintargument with a default value that is the value r...

return default的用法就是在默认情况下返回一个合理的值。这个值可以是一个基础类型的默认值,比如0、false或null,也可以是一个对象的默认实例。 使用return default可以在程序遇到未定义的情况时提供一个明确的返回值,以避免程序出错或产生意外结果。这可以增加程序的健壮性,并使程序更容易维护和调试。 以下是一个简...

The"redefinition of default parameter"error in C++ occurs when you attempt to provide a default value for a function parameter in multiple places, such as within both the function declaration and its definition. This conflict leads to ambiguity for the compiler and results in the error. ...
