WebApr 6, 2024 · Conclusion: In summary, a custom assignment operator in C++ can be useful in cases where the default operator is insufficient or when resource management, memory allocation, or inheritance requires special attention. It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states. WebExpression-equivalent. Expression e is expression-equivalent to expression f, if . e and f have the same effects, and ; either both are constant subexpressions or else neither is a constant subexpression, and ; either both are potentially-throwing or else neither is potentially-throwing (i.e. noexcept (e) == noexcept (f)).
