请教各位大侠ＡＩＸ下编Ｃ＋＋怎么会不识别string类型？？

lonely_wolf

我在ＡＩＸ下编绎一个简单的Ｃ＋＋程序时，报string为不识别类型，我在程序中已经包含了＜string＞头文件了呀．请各位大侠指点一下！

使用using namespace std;没有？
还有有c＋＋编译器吗？

lonely_wolf

没有用ＳＴＤ
用的ＡＩＸ的xlC_r编译的．

lonely_wolf

请问using namespace std;这句怎么加了，我在程序中按教材上的加上不对呀．

#include <string>
using namespace std;
你看的什么教材？

最好把你的代码和编译的指令和错误的信息
贴出来。
哈哈。。
这样比较快。。。

  using namespace std;
