This chapter discusses exception handling in C++. It introduces exceptions as undesirable events detectable during program execution. Try/catch blocks are used to handle exceptions, where code that may trigger exceptions is placed in a try block and catch blocks specify the exception type and contain handling code. Catch blocks are checked in order to handle matching exceptions. The chapter covers built-in C++ exception classes and creating custom exception classes, as well as rethrowing, stack unwinding, and different techniques for exception handling.
