我试图将数据从网页复制到结构数组中并在生成数据之前按“名称”进行排序。当我运行这个程序时,它说按任意键继续?这个程序为什么提示我'按任意键继续'?
#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
此代码没有任何**与网页。它从文件中读取“珠宝”数据并按名称排序。 'system'(“pause”)行让程序在退出之前等待按键。 – egrunin 2010-05-06 17:20:23
yyes它读取珠宝数据并对其进行排序..但是,当它被编译并且什么也没有显示时除了按任何键以外继续 – Taylor 2010-05-06 18:09:34
您期待什么结果?您的问题需要更新以获取更多信息。 – Sampson 2010-05-06 19:23:30
