异常处理是C++中一个重要的特性,它允许程序在遇到错误时以一种可控的方式进行恢复,而不是直接崩溃。C++提供了一套完整的异常处理机制,包括抛出(throw)、捕获(catch)和异常规格说明(exception specifications)。本文将深入探讨C++中的异常处理,包括异常安全性、错误处理策略以及如何使用异常处理来提高程序的健壮性。 异常...
[string.erase]:Throws:length_errorifn > max_size(). There are a few things referenced in the “…” portion of[container.requirements.general](11), but they do not apply tobasic_string. Hooray, we can use theerasemethod to shrink the string and avoid an exception. void remove_extension(...

接下来, 我们在 main 中设置一个断点, 然后运行该程序, 如下所示: (gdb) break main Breakpoint 1 at... __cxa_allocate_exception 时导致断点, 从源文件 excp.c 的第13行调用。通过移动一个栈帧, 我们可以看到触发异常的原始代码行: (gdb) up #1 0x0804878c in main () at...
若std::decay<T>::type 是非final 、非 union 、既非 std::nested_exception 亦非从 std::nested_exception 导出的类类型,则抛出一个从 std::nested_exception 和std::decay<T>::type 两者公开导出的未指定类型的异常,从 std::forward<T>(t) 构造。 nested_exception 基类的默认构造函数调用 std::current...
