explicit ConstructorsA constructor that takes a single argument is,by default,an implicit conversion operator,which converts its argument toan object of its class (see also Chapter 3,"Operator Overloading"). Examine the following concrete example:class string{private:int size;int capacity;char *bu...
1)For operator overloading to work, at least one of the operandsmust be a user defined class object. 2)Assignment Operator:Compiler automatically creates a default assignment operator with every class. The default assignment operator does assign all members of right side to the left side and wo...
6. 运算符重载(Operator Overloading)C++的运算符重载必须确保操作数与重载定义的类型匹配,否则会导致编译错误。 C++在类型检查方面提供了更严格和安全的机制,强化了编译时的错误捕捉能力,减少了类型错误和指针错误导致的运行时错误的可能性。这些机制在大型软件开发中显得尤为关键,因为它们帮助保持了代码的健壮性和易...

It could have potentially caused a crash or unexpected behavior at runtime, because the compiler incorrectly called the wrong overload of the operator. In Visual Studio 2017, a compiler error is raised. The specific error might vary, but a typical error is C2672, "no matching overloaded ...
v Implicit conversion between decimal floating-point types and real binary floating-point types is only allowed via assignment, with the simple assignment operator =. Implicit conversion is performed in simple assignments, which also include function argument assignments and function return values. End ...
