我試圖將數據從網頁複製到結構數組中並在生成數據之前按「名稱」進行排序。當我運行這個程序時,它說按任意鍵繼續?這個程序爲什麼提示我'按任意鍵繼續'?
#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;
inFile>> product[x].size;
inFile>> product[x].amount;
inFile>> product[x].group;
// cout << product[x].itemCode << ", " << product[x].name << ", "<< product[x].size << ", " << product[x].amount << endl;
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
此代碼沒有任何**與網頁。它從文件中讀取「珠寶」數據並按名稱排序。 'system'(「pause」)行讓程序在退出之前等待按鍵。 – egrunin 2010-05-06 17:20:23
yyes它讀取珠寶數據並對其進行排序..但是,當它被編譯並且什麼也沒有顯示時除了按任何鍵以外繼續 – Taylor 2010-05-06 18:09:34
您期待什麼結果?您的問題需要更新以獲取更多信息。 – Sampson 2010-05-06 19:23:30
