integer literal的后缀有点问题,但不想改了。 如果用cursor,用logos开发和AI写个lexer耗时差不多。
%= Modulus then assign It performs modulus and then result is assigned to left hand operand I%=Jthat means I = I % J <<= Left shift AND assignment operator It performs Binary left shift and then result is assigned to left hand operand I<<=5that means I = I << 5 >>= Right shif...
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...

If you think you need a virtual assignment operator, and understand why that's deeply problematic, don't call it operator=. Make it a named function like virtual void assign(const Foo&). See copy constructor vs. clone(). 如果你认为你需要一个虚赋值操作运算符,而且理解它会产生很深刻的问题,...
Operator overloadability Theis,as, andtypeofoperators can't be overloaded. A user-defined type can't overload the()operator, but can define custom type conversions performed by a cast expression. For more information, seeUser-defined conversion operators. ...
