The basic idea behind exception handling is to separate the normal flow of program execution from error-handling code. Instead of terminating the program abruptly when an error occurs, C++ provides a way to “throw” an exception, representing the error or exceptional condition. The thrown exceptio...

Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
What should I do if garbled characters are displayed in HiLog information? How do I analyze fault logs (such as JSCrash, CppCrash, and Appfreeze)? How do I locate the fault when the application crashes? Which one is recommended for logging, HiLog or console? How do I set the dom...
A Destructor in C++ is a member function having the same name as that of the constructor. But, it is preceded by a tilde (~) symbol.
The main improvements are in enabling NRVO for cases which involve exception handling or loops. For example, in 17.3, the copy/move of result when returning it would not be elided, but now will be. Copy Foo ReturnInALoop(int iterations) { for (int i = 0; i < iterations; ++i) { ...
What is uncaught exception in C++? The exception handling subsystem calls the function:unexpected(). This function, provided by the default C++ library, defines the behavior when an uncaught exception arises. By default, unexpected calls terminate(). The terminate function defines the actions that ...
overload here is some facility to create an overload set from multiple lambdas, and is commonly used for variant visitation. See cppreference, for example. This counts the number of leaves in the tree through recursion. For each function call in the call graph, if the current is a Leaf,...
