C++设计选择排序算法代码

以下是C++实现选择排序算法的代码：

#include <iostream>
using namespace std;

void selectionSort(int arr[], int n) {
    int i, j, min_idx;
    for (i = 0; i < n-1; i++) {
        min_idx = i;
        for (j = i+1; j < n; j++)
            if (arr[j] < arr[min_idx])
                min_idx = j;
        swap(arr[min_idx], arr[i]);
    }
}

int main() {
    int arr[] = {64, 25, 12, 22, 11};
    int n = sizeof(arr)/sizeof(arr[0]);
    selectionSort(arr, n);
    cout << "Sorted array: \n";
    for (int i=0; i < n; i++)
        cout << arr[i] << " ";
    return 0;
}
