想让a和b进行100次随机的石头剪刀布，然后输出输赢，但是我定义的数组却在运行过程中被破坏，后来又试了一种方法，就是把数组的指针传到函数中去，加上了const，代码如下，但数组还是被破坏了，不知为何，请教大神。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

void method(const int * const a, const int * const b, int *x,int *y);

int main()
{
    int a[100], b[100];        /*存储每次石头剪刀布的结果，0-石头，1-剪刀，2-布*/
    int x = 0, y = 0;        /*a、b胜利的次数*/
    int    i = 0;
    srand(time(NULL));
    for (i = 0;i < 100;i++)    /*100 times of game.*/
    {
        a[i] = rand() % 3;
        b[i] = rand() % 3;
        printf("a[%2d] = %d\tb[%2d] = %d\n", i, a[i], i, b[i]);
    }

    method(a,b,&x,&y);

    printf("%d\t%d", x, y);

    if (x > y)
    {
        printf("A wins!\n");
    }
    else if(y>x)
    {
        printf("B wins!\n");
    }
    else if (x = y)
    {
        printf("Both wins!\n");
    }
    else
    {
        printf("\aERROR!\n");
        Sleep(1000);
        exit(0);
    }

    _getch();
    return 0;
}

void method(const int * const a, const int * const b, int *x, int *y)
{
    int i = 0;
    for (i = 0;i < 100;i++)
    {
        switch (*(a+i))
        {
        case 0:
            switch (*(b+i))
            {
            case 0:break;
            case 1:(*x)++;
                break;
            case 2:(*y)++;
                break;
            default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }
        case 1:
            switch (*(b+i))
            {
            case 0:(*y)++;
                break;
            case 1:break;
            case 2:(*x)++;
                break;
            default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }
        case 2:
            switch (*(b+i))
            {
            case 0:(*x)++;
                break;
            case 1:(*y)++;
                break;
            case 2:break;
            default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }
        default:printf("ERROR!\n");
            Sleep(1000);
            printf("\a");
            exit(0);
        }
    }
}

如图，我的数组元素全被破坏掉了；

By the way. 我VS2015的智能提示没有了，就消失掉了，现在好麻烦。

//这种switch嵌套容易造成混乱break~~~~

void method(const int * const a, const int * const b, int *x, int *y)
{
    int i = 0;
    for (i = 0;i < 100;i++)
    {
        switch (*(a+i))
        {
            case 0:
            switch (*(b+i))
            {
                case 0:break;
                case 1:(*x)++;break;
                case 2:(*y)++;break;
                default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }break;
            case 1:
            switch (*(b+i))
            {
                case 0:(*y)++;break;
                case 1:break;
                case 2:(*x)++;break;
                default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }break;
            case 2:
            switch (*(b+i))
            {
                case 0:(*x)++;break;
                case 1:(*y)++;break;
                case 2:break;
                default:printf("ERROR!\n");
                Sleep(1000);
                printf("\a");
                exit(0);
            }break;
            default:printf("ERROR!\n");
            Sleep(1000);
            printf("\a");
            exit(0);
        }
    }
}
