关于LNK2001的问题，请高手指点

[九个太阳2023]

该程序就是对"abc.txt"里的数据的最大公约数进行排序，然后输出，附"abc.txt"文件：
12 35
77 91
123 789
24 28
64 112
1024 888
98 54

************************************************下面是我的程序
#include <iostream>
#include <fstream>
#include <vector>
#include <algorithm>
#include <sstream>
using namespace std;

typedef vector<int> VI;
typedef vector<VI> VVI;

int DivisorNumber(int x,int y);
void InputData(VVI&);
void print(VI&);
vector<int> Fun(vector<VI>& a);

int main()
{
VVI matrix;
InputData(matrix);

VI Vec;
Vec = Fun(matrix);
sort(Vec.begin(),Vec.end());
print(Vec);

return 0;
}

//求取两个整数的最大公约数
int DivisorNumber(int x,int y)
{
//辗转相除法
int m,n,t;
if (x > y)
{
m = x;
n = y;
}
else
{
m = y;
n = x;
}

while (m % n != 0)
{
t = n;
n = m%n;
m = t;
}

return n;
}

void InputData(VVI&m)
{
ifstream in("abc.txt");
int t;
m.resize(7);
for (string s;getline(in,s);)
{
for (istringstream sin(s);sin>>t;m[m.size()-8].push_back(t));
}
}

vector<int> Fun(vector<VI>& a)
{
vector<int> c(7);

for (int i = 0; i < 7; ++i)
{
c[i] = DivisorNumber(a[i][0],a[i][1]);
}

return c;
}

在编译的时候出现下列错误：

print函数你没有实现
