在此范围内未声明的打印

Question

无论何时我编译文件，编译器都会告诉我，我的打印未在此范围内声明。问题是我无法触摸我的主文件，因为它属于我的学校。有谁知道该怎么办？谢谢！

编译器错误消息：

main.cpp: In function ‘void TestPush()’:
main.cpp:10:5: error: ‘Print’ was not declared in this scope
 Print(a);
 ^~~~~

在我的.h文件中：

template <typename T>
class vector 
 {

private:
    T* v;
    int count;
    int capacity;
public:

vector(int capacity)
: v(new T[capacity]), count(0) {}

void Print(vector<T> s) {
    for(int i = 0; i < count; i++) 
    {
    std::cout<<v[i]<<" ";
    }
    std::cout<< "(size=" << size << "," << "capacity=" << capacity << ")";

}
}

在我的主文件中：

#include <iostream>
#include <cstdlib>              // atoi
#include "cs150_vector.h"

void TestPush(void)
{
std::cout << "\n********** TestPush **********\n";
cs150::vector<float> a;
std::cout << "Empty array:\n";
Print(a);

std::cout << "push_back 5 floats:\n";
for (float i = 0; i < 5; i++) {
    a.push_back(i);
    Print(a);
}

std::cout << "pop_back until empty:\n";
while (!a.empty()) {
    a.pop_back();
    Print(a);
}

}
