std::cerr << "Caught exception: " << e.what()<< std::endl; } return 0; } 在这个示例中,我们首先包含了必要的头文件,然后在main函数中使用try和catch块来捕获异常。在try块中,我们抛出一个std::runtime_error异常,并在catch块中捕获它。 在catch块中,我们可以使用what()函数来获取异常的描述信息...
在C++中,异常处理就是使用try catch及 throw三个关键字来实现,对于try,在语法分析阶段被消化掉,在汇编代码中,try的位置没有而外的代码体现,而只是在附加的exception_table中有相应的结构定界体现,表示这个结构中的代码是受保护的代码,并且如果它有对应的catch,那么catch处有相应的action table结构。 与此相反,对于...

region. For example, in C++, an exception thrown by a destructor during stack unwinding is required to result in a call to `std::terminate', so the C++ version of this function returns a FUNCTION_DECL for `std::terminate'. */
如果在调试过程中某些库无法定位到源文件,例如 std::string 组件就定位到了我的编译目录. 像这样: /root/gcc-4.9.3/gcc-build-4.9.3/x86_64-unknown-linux-gnu/libstdc++-v3/include/bits/basic_string.h: No such file or directory /root/gcc-4.9.3/gcc-build-4.9.3/x86_64-unknown-linux-gnu/libstd...
To enable C++17 support, add the command-line parameter -std=c++17 to your g++ command line. Or, to enable GNU extensions in addition to C++17 features, add -std=gnu++17.Important: Because the final ISO C++17 standard is still new, GCC's support is experimental. No attempt will be ...
floating point exception 中文含义:浮点运算异常 错误原因:这是个算术运算异常。如除数为0,上溢、下溢或非法的操作(如对-1 求平方根)。 Illegal instruction 中文含义:非法指令 错误原因:当系统遇到非法的机器指令时,产生此错误。通常此类错误是在源 代码已编译成特定机器的目标代码后,又在其它类型的机器上运行时...
