Operator overloads are intended to provide an intuitive interface to your user-defined types (classes). So just as you can add two integers together using the plus operator, you should be able to do the same with your user-defined data types. However, not all operators will make sense to all objects. For instance, if the sum of two objects cannot be easily defined then it makes no sense to provide an addition operator. E.g., fruit = apple + orange would not make any sense in the real world, but float = apple + 1.25 might make sense if the primary member of apple were its price or its weight, or some other numeric value. Ultimately, an operator must be both intuitive and predictable in order to be useful. If not, then a more self-explanatory method (function) would be better than an operator overload.
What else can I help you with?
Why certain operators cannot be overloaded?
Because certain operators, such as new and sizeof must provide predictable results. Overloading them would achieve nothing except to introduce unpredictability, thus overloading is not permitted.
Why ternary operator is not overloaded?
The ternary operator (known as the conditional operator in C++) cannot be overloaded because it is impossible to pass a test operand and two expression operands (either or both of which may be comma-separated) to a function. You can only pass values or references as arguments to a function. Even if it were possible, built-in functions and operators that rely on the conditional operator would likely break. Like all the other operators that cannot be overloaded (sizeof, typeid, ::, . and .*) the results must always be predictable because built-in operators and functions rely on them so heavily.
What is the operator that cannot be overloaded?
There are 5 operators which cannot be overloaded. They are: * .* - class member access operator * :: - scope resolution operator * . - dot operator * ?:: - conditional operator * Sizeof() - operator Note:- This is possible only in C++.
Why is it that every answer-page has to be so overloaded with advertising to the point of not being able to get the answer?
The reason why every answer-page is overloaded with advertising to the point of not being able to get answers is that the host of the website allows.
What are special operators in c plus plus?
The only "special" operators in C++ are those that cannot be overloaded. That is; the dot member operator (.), pointer to member operator (.*), ternary conditional operator (:?), scope resolution operator (::), sizeof() and typeof().
Which operator not overloaded in c plus plus?
The if statementex.if (index < 5)printf("Index is less than 5\n");elseprintf("index is greater or equal to 5\n");(You can also replace the "if" with a "?" and the "else" with a "?" -- no, that would be syntax error)
