[Js-C++]C++中赋值表达式的结果

C++中所赋的值即是赋值表达式的结果

在看数据结构的时候看到冒泡排序一种奇怪的写法,不明所以,被循环条件弄得很懵,才想起来这个结论:

#include <iostream>

using namespace std;

void swap(int &a, int &b) {
    int temp = b;
    b = a;
    a = temp;
}

void bubblesort(int A[], int n) {
    int t = n;
    for (bool sorted = false; sorted = !sorted; n--) {
        for (int i = 1; i < n; ++i) {
            if (A[i - 1] > A[i]) {
                swap(A[i - 1], A[i]);
                sorted = false;
            }
        }
    }
    for (int j = 0; j < t; ++j) {
        cout << A[j] << " ";
    }
}

int main() {
//    int A[] = {5, 6, 7, 4, 2, 8};
    int A[] = {2, 4, 5, 6, 7, 8};
    bubblesort(A, sizeof(A) / sizeof(int));
    return 0;
}
