當我運行這個程序時，它說「按任意鍵繼續」？

Question

#include <iostream> 
#include <string> 
#include <iomanip> 
#include <fstream> 
using namespace std; 


struct productJewelry 
{ 
     string name; 
     double amount; 
     int itemCode; 
     double size; 
     string group; 
}; 


int main() 
{ 
    // declare variables 
    ifstream inFile; 
     int count=0; 
     int x=0; 


     productJewelry product[50]; 

    inFile.open("jewelry.txt"); // file must be in same folder 
    if (inFile.fail()) 
     cout << "failed"; 
    cout << fixed << showpoint; // fixed format, two decimal places 
    cout << setprecision(2); 



    while (inFile.peek() != EOF) 
    { 
//   cout << count << " : "; 
     count++; 
     inFile>> product[x].itemCode; 
     inFile>> product[x].name;

     x++; 
     if (inFile.peek() == '\n') 
      inFile.ignore(1, '\n'); 

    } 

    inFile.close(); 
string temp; 
bool swap; 
     do 
     { 
      swap = false; 
      for (int x=0; x<count;x++) 
      { 
      if (product[x].name>product[x+1].name) 
      { 
       //these 3 lines are to swap elements in array 
       temp=product[x].name; 
       product[x].name=product[x+1].name; 
       product[x+1].name=temp; 
       swap=true; 
      } 
      } 
     } while (swap); 


     for (x=0; x< count; x++) 
     { 
     //cout<< product[x].itemCode<<" "; 
     //cout<< product[x].name <<" "; 
     //cout<< product[x].size <<" "; 
     //cout<< product[x].amount<<" "; 
     //cout<< product[x].group<<" "<<endl; 

     } 

    system("pause"); // to freeze Dev-c++ output screen 
    return 0; 
} // end main 

需要打印，並進行排序在按字母順序排列
