背景 惨痛的背景,正如我前面提到的,参加了公司的一个训练营.刚进来公司的新人,内心充满着对未来的美好憧憬,期待自己能闯出属于自己的天地.更何况,作为一名程序员,无比的希望所有人对自己写得代码或者App都有膜拜式的认可.However,这些期待,都在这次训练营中破灭了,迎接我的,就是答辩嘉宾的不耐烦,和呵呵一笑···痛定思痛吧,总需要对自己做的不足进行反思的······吧啦吧啦,前面说了一堆垃圾,因为我们训练营做的是一个实时地理信息分享这么一个主题的Demo,面试官当场就问了我,这个“技术人员”一…

Linux开发中常见段错误问题原因分析 1 使用非法的内存地址(指针),包括使用未经初始化及已经释放的指针.不存在的地址.受系统保护的地址,只读的地址等,这一类也是最常见和最好解决的段错误问题,使用GDB print一下即可知道原因. 2 内存读/写越界.包括数组访问越界,或在使用一些写内存的函数时,长度指定不正确或者这些函数本身不能指定长度,典型的函数有strcpy(strncpy),sprintf(snprint)等等. 3 对于C++对象,应该通过相应类的接口来去内存进行操作,禁止通过其返…
