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...
答:接口可以继承接口。抽象类可以实现(implements)接口,抽象类是否可继承实体类,但前提是实体类必须有明确的构造函数。 41.构造器Constructor是否可被override? 答:构造器Constructor不能被继承,因此不能重写Overriding,但可以被重载Overloading。 42.是否可以继承String类? 答:String类是final类故不可以继承。 43.try ...
>= Greater than or equal to If the value of left operand is greater than or equal to the value of right operand then it returns true. I = 40, J =20(I >= J) is True 3. Logical Operators in C Operator Operator Name Description Example and Logical AND When Both side condition is ...
For example, overloading func(const pair<int, int>&) and func(const pair<string, string>&), and calling func() with pair<const char *, const char *> will compile with this change. However, this change breaks code that relied on aggressive pair conversions. Such code can typically be ...

In C the type of character literals are int and char in C++. 在C语言中，字符文字的类型在C ++中为int和char 。 This is in C++ required to support function overloading . 这是C ++中支持函数重载所必需的。 See this example: void foo(char c){undefined puts("char");} void foo(int i){...
