出于某种原因,我无法正确获得这种名称。谁能告诉我它有什么问题?据我所知,问题是没有正确比较字符串。我之前尝试过字符串比较,我知道这种代码应该可以工作。这真的让我难过。
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
void sortNames(vector<string> &);
void main()
{
vector<string> namesList;
ifstream namesFile;
namesFile.open("Names.txt");
// Make sure the file exists.
if (namesFile)
{
// Get the names from the file.
string name;
while (getline(namesFile, name))
namesList.push_back(name);
// Sort the imported names.
sortNames(namesList);
for (int i = 0; i < namesList.size(); i++)
cout << namesList[i] << endl;
}
else
{
cout << "Data files are missing";
}
namesFile.close();
}
void sortNames(vector<string> &list)
{
for (int i = 0; i < list.size(); i++)
{
// Find the lowest value after i.
int lowIndex = i;
for (int j = i + 1; j < list.size(); j++)
{
string name = list[i];
string name2 = list[j];
if (name > name2)
lowIndex = j;
}
// Flip the elements if there was a value lower than i.
if (i != lowIndex)
{
string temp = list[i];
list[i] = list[lowIndex];
list[lowIndex] = temp;
}
}
}
