这可能只是一个我没有看到的简单错误，但我认为我只是做错了什么。别担心，我没有在我的标头函数中使用命名空间 std 或任何似乎是这个人的问题的东西 [我读到的问题与我的类似][1] [1]：为什么我得到字符串没有命名类型错误?
我现在收到 4 个错误：
C:\Documents and Settings\Me\My Documents\C++Projects\C++\RandomSentence\Nouns.h|8|错误：命名空间“std”中的“字符串”未命名类型|
C:\Documents and Settings\Me\My Documents\C++Projects\C++\RandomSentence\Nouns.h|12|错误：命名空间“std”中的“字符串”未命名类型|
C:\Documents and Settings\Me\My Documents\C++Projects\C++\RandomSentence\Nouns.h|13|错误：命名空间“std”中的“字符串”未命名类型|
C:\Documents and Settings\Me\My Documents\C++Projects\C++\RandomSentence\Nouns.cpp|9|error: no 'std::string Nouns::nounGenerator()' member function声明在类'Nouns' |
||=== 构建完成：4 个错误，0 个警告 ===|
这是我的头文件：
class Nouns
{
public:
Nouns();
std::string noun;
protected:
private:
int rnp; // random noun picker
std::string dog, cat, rat, coat, toilet, lizard, mime, clown, barbie, pig, lamp, chair, hanger, pancake, biscut, ferret, blanket, tree, door, radio;
std::string nounGenerator()
};
这是我的 cpp 文件：
#include "Nouns.h"
#include <iostream>
Nouns::Nouns()
{
}
std::string Nouns::nounGenerator(){
RollRandom rollRandObj;
rnp = rollRandObj.randNum;
switch(rnp){
