【C++】指针进行数组冒泡排序

#include <iostream>
using namespace std;
#include <string.h>

void bubbleSort(int* a, int len) {
	for (int i = 0; i < len - 1; i++)
	{
		for (int j = 0; j < len - 1 - i; j++) {
			if (a[j] > a[j + 1]) {
				int temp = a[j + 1];
				a[j + 1] = a[j];
				a[j] = temp;
			}
		}
	}
}

void printa(int* a, int len) {
	cout << "排序后的数组" << endl;
	for (int i = 0; i < len; i++) {
		cout << a[i] << endl;
	}
}
int main() {
	int a[] = { 1,2,3,8,7,9,4 };
	int len = sizeof(a) / sizeof(a[0]);
	bubbleSort(a,len);
	printa(a,len);
	system("pause");
	return 0;
