A pass by reference can be coded via references or pointers as function parameters. A parameter of a reference type is an alias for an argument. When a function is called, a reference parameter is initialized with the object supplied as an argument. The function can directly manipulate the ar...

If the l modifier is used, the argument is first converted to a character string as if by %ls with a wchar_t[2] argument. N/A N/A int wint_t N/A N/A N/A N/A N/A s Writes a character string. The argument must be a pointer to the initial element of an array ...
20:最好用pass-by-reference-to-const替换pass-by-value 1.引用传值,本质上也是传递一个指针,如果是传递内置类型,就不如采用直接传值了。(另外STL的迭代器和函数对象也是) 2.用引用传值通常比较高效,并可避免切割问题。 3.切割问题:当使用传值方式时,一个子类对象被传递,被当一个父类对象接收时,此时只能调...
宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...

The shared_pointer is a reference counting smart pointer that can be used to store and pass a reference beyond the scope of a function. This is particularly useful in the context of OOP, to store a pointer as a member variable and return it to access the referenced value outside the ...
