因此，我尝试将 int 添加到错误的来源，但这只会增加大量新错误。我用谷歌搜索了一下，但我没有找到任何对我有帮助的东西，或者我只是不明白很多人在说什么。
#include <iostream>
#include <string>
using namespace std;
//Define the stack class, set default stack size to 7
//use a template to define type at later point
template<class T,int size=7>
class stack
{
private: T data[size];
int stack_ptr;
public:
stack(void);
void push(T x);
T pop();
T top();
};
//constructor function to initialize stack and data
template<class T, int size>
stack<T, size>::stack(void)
{
int i;
for(i=0;i<size;i++) data[i]=0;
stack_ptr=0;
}
//Push data onto stack
template<class T,int size>
void stack<T, size>::push(T x)
{
if(stack_ptr>=size)
{
cout<<"cannot push data: stack full"<<endl;
return;
}
data[stack_ptr++]=x;
cout<<"Pushed\t" << x << "\tonto the stack"<<endl;
return;
}
//Pop data from stack
template<class T, int size>
stack<T, size>::pop()
{
using namespace std;
if(stack_ptr<=0)
{
cout<<"cannot pop data: stack empty"<<endl;
return data[0];
}
cout<<"popped\t"<< data[--stack_ptr]<< "\tfrom stack"<<endl;
return data[stack_ptr];
}
int main()
{
//declaring stack of strings and using default size
stack<string> c;
string w;
string name1 = "Rich";
string name2 = "Debbie";
string name3 = "Robin";
string name4 = "Dustin";
string name5 = "Philip";
string name6 = "Jane";
string name7 = "Joseph";
c.push(name1);
c.push(name2);
c.push(name3);
c.push(name4);
c.push(name5);
c.push(name6);
c.push(name7);
//pick up the stack value
w=c.pop();
string & i = c.top( );
string next_top = c.top();
cout << "The top person the stack is " << next_top << "."<< endl;
return 0;
}
这是我的错误

我不确定我还能做什么，任何帮助表示赞赏。
