我们可以operator++为预增量和后增量重载吗?即正确调用SampleObject++和++SampleObject结果. class CSample { public: int m_iValue; // just to directly fetch inside main() CSample() : m_iValue(0) {} CSample(int val) : m_iValue(val) {} // Overloading ++ for Pre-Increment int /*CSample...
我想知道这是否是重载post和pre increment运算符的正确代码. 如何在main()中调用这些运算符. class fix{ int x; int y; public:fix(int = 0, int = 0); fix operator++(){//prefix increment fix a; ++a.x; ++a.y; return a; } fix operator++(int){ //post fix increment fix c; c.x =...
The increment and decrement operators fall into a special category because there are two variants of each: Preincrement and postincrement Predecrement and postdecrement When you write overloaded operator functions, it can be useful to implement separate versions for the prefix and postfix versions ...
Before getting to the details of operator overloading, let's first see how the line above would be enabled forTimeOfDay. What is needed is to redefine theincrement()member function under the special nameopOpAssign(string op)and also to specify that this definition is for the+character. As ...
1 Esistono due versioni degli operatori di incremento e decremento unario: preincrement e postincrement.Per altre informazioni, vedere Regole generali per l'overload degli operatori. Negli argomenti seguenti vengono descritti i vincoli per le diverse categorie di operatori di overload:...

If the motor speed is too slow, the overload warning flag No. 3 is tested. If flag No. 3 is set, a very small conduction angle adjustment is made to permit the motor speed to ramp up slowly. A 0.864° conduction angle increment per line cycle is presently preferred. This is used to...
