在一个数组中将数据打乱

#include <stdio.h>
#include<string.h>

void printArray(int *arry, int n) {
	for (int i = 0; i < n; i++) {
		printf("%d ", arry[i]);
	}
}

int main() {
	int arry[11] = { 1,2,3,4,5,6,7,8,9,10,11 };
	srand(time(0));
	for (int i = 0; i < 11; i++) {
		int r = rand() % 11;
		int t = arry[i];
		arry[i] = arry[r];
		arry[r] = t;
	}
	printArray(arry, 11);
	return 0;	
}
