#include <iostream>
#include <string>

using namespace std;

void bubbleSort(int data[], int n);

int main()
{
cout << "Enter ten unsorted integers..." << endl;

int a[10];
for (int i = 0; i < 10; ++  i)
{
    cout << "[" << i << "] = ";
    cin >> a[i];
}

cout << endl << "Unsorted List = ";
    for (int i = 0; i < 10; ++i)
    cout << a[i] << ", ";

cout << endl;

cout << "Sorting..." << endl;
cout << "Sorted List = ";
bubbleSort(a, 10);
}

void bubbleSort(int data[], int n)
{
int j = 0;
bool nextEnd = true;
while (nextEnd)
{
    nextEnd = false;
    ++j;
    for (int i = 0; i < n - j; ++i) 
    {
        if (data[i] > data[i+1]) 
        {
            int temp = data[i];
            data[i] = data[i+1];
            data[i+1] = data[i];
            nextEnd = true;
        }
    }
}

for (int i = 0; i < 10; ++i)
cout << data[i] << ", ";
}

程序非常简单。向数组输入十个值。显示未分类。将它们发送到bubbleSort函数,对它们进行排序,最后显示排序列表。我遇到的问题是我没有让输出恢复工作。我测试了最后一行代码,但这不起作用。我不认为我的排序也搞砸了。如何正确显示此排序列表?

答案 0 :(得分:3)

冒泡排序中至少有一个错误。 data[i+1]的分配不正确。它应该是:

data[i+1] = temp;

答案 1 :(得分:2)

问题是你的“交换”。它应该是:

int temp = data[i];
data[i] = data[i+1];
data[i+1] = temp;

编辑测试并正常修正。
