请C++高手来看看我的这串代码哪里出错了

Question

头文件：C++顺序串.h
class string{
public:
string();
int length() const;
int get_int(const int i,char &x) const;
int locate(const char x) const;
int insert(const int i,const char x);
int delete_int(const int i);
int QuickSortTheList(); //这是一个用来对表进行快速排序的函数
int QuickSortTheList200();
private:
char data[1000]; //maxlen取1000
int count;
};
string::string(){count=0;}
int string::length() const
{return count;}
int string::get_int(const int i,char &x)const{
if(i<=0||i>count) return -1;
x=data[i-1];
return 1;
}
int string::locate(const char x)const{
for(int i=0;i<length();i++)
if(data[i]==x) return(i+1);
return -1;
}
int string::insert(const int i,const char x){
if(count==1000)
return 0;
if(i<1||i>length()+1)
return 0;
for(int j=count-1;j>=i-1;j--)
data[j+1]=data[j];
data[i-1]=x;
count++;
return 1;
}
int string::delete_int(const int i){
if(length()==0)
return 0;
if(i<1||i>length())
return 0;
for(int j=i+1;j<=length();j++)
data[j-2]=data[j-1];
count--;
return 1;
}

下面是一个实验locate函数好不好用的cpp:
#include<iostream>
using namespace std;
#include"C++顺序串.h"
int main()
{
string a;
for(i=1;i<=10;i++)
{
char m;
cin>>m;
a.insert(m,i);
}
char q;
cout<<"请输入要查找的字符";
cin>>q;
cout<<a.locate(q)<<endl;
}

程序无法运行，下面是错误提示：

我用的编译器是GCC，软件是Sublime Text。

Answer 1

#include<iostream>
using namespace std;
class string{

};
int main(){
string a;
return 0;
}
//我的sublime用的是g++，测了这一段代码，都报错了。
//[第一个错误]error: reference to 'string' is ambiguous
//我不知道我的理解有没有错啊，你的自己定义的类string和std namespace里面的string同名了。  
//希望帮到你！
