有时候编译C++,会遇到错误,undefined reference 错误。 怎么定位这个错误呢?本文介绍如何使用nm, c++filt定位链接报错。 本文以undefined reference to SetFirstChanceExceptionHandler报错为切入点。 基础知识 C++,一般会将声明和定义分开,比如函数的声明在头文件中,但是函数定义却在cpp文件中。 这种分开具有历史因素。现在...

In the examples from the previous page, we used normal variables when we passed parameters to a function. You can also pass areferenceto the function. This can be useful when you need to change the value of the arguments: Example
