Объединение одного типа в C++
Whenever I see examples of union, they are always different types. For example, from MSDN:
// declaring_a_union.cpp union DATATYPE // Declare union type { char ch; int i; long l; float f; double d; } var1; // Optional declaration of union variable int main() { } What happens if I have a union (in this case anonymous, but that shouldn't matter) like this:
union { float m_1stVar; float m_1stVarAlternateName; }; Regardless of whether this is good practice or not, will this cause any issues?
