意思是：在"{"的前面少了一个“；copy”，把“；”补上，错误即可消失。错误示例：1、error: expected expression before ‘/’ token和In function ‘main’.意思是：C++的语法错误。2、expected initializer before '<' token.意思是：借鉴里面问没有指定名字空间的问题，重新把boost库的路径放到了...
sectionA.section_name，sectionA.locations这是常量地址你怎么给他赋值？？最重要一点就是对于结构体内的数组，只能在函数体内进行赋值，在函数体外只能初始化，所以你这样赋值是肯定编译不过的 我改了下程序如下：vs2010调试无误 struct Section{ char section_name[10];double locations[4][2];};i...
