  2. Most vexing parse - Wikipedia

    en.wikipedia.org/wiki/Most_vexing_parse

    The most vexing parse is a counterintuitive form of syntactic ambiguity resolution in the C++ programming language. In certain situations, the C++ grammar cannot distinguish between the creation of an object parameter and specification of a function's type. In those situations, the compiler is required to interpret the line as a function type ...

    /* will print the provided char string as expected using ADL derived from the argument type std::cout */ operator << (std:: cout, "Hi there") /* calls a ostream member function of the operator<< taking a void const*, which will print the address of the provided char string instead of the content of the char string */ std:: cout. operator ...

  4. Dangling else - Wikipedia

    en.wikipedia.org/wiki/Dangling_else

    The dangling else is a problem in programming of parser generators in which an optional else clause in an if–then(–else) statement can make nested conditional statements ambiguous. Formally, the reference context-free grammar of the language is ambiguous, meaning there is more than one correct parse tree.

  5. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.

  6. Virtual inheritance - Wikipedia

    en.wikipedia.org/wiki/Virtual_inheritance

    As declared above, a call to bat.Eat is ambiguous because there are two Animal (indirect) base classes in Bat, so any Bat object has two different Animal base class subobjects. So, an attempt to directly bind a reference to the Animal subobject of a Bat object would fail, since the binding is inherently ambiguous:

  7. Input/output (C++) - Wikipedia

    en.wikipedia.org/wiki/Input/output_(C++)

    In the C++ programming language, input/output library refers to a family of class templates and supporting functions in the C++ Standard Library that implement stream-based input/output capabilities. [ 1 ] [ 2 ] It is an object-oriented alternative to C's FILE -based streams from the C standard library .

  8. Ambiguity - Wikipedia

    en.wikipedia.org/wiki/Ambiguity

    Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "... Only in the context of a proposition has a name meaning." [7] A highly confusing term is gain. For example, the sentence "the gain of a system ...

  9. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    The same function name is used for more than one function definition in a particular module, class or namespace; The functions must have different type signatures, i.e. differ in the number or the types of their formal parameters (as in C++) or additionally in their return type (as in Ada).
