C语言：给定一个数组，逆序输出该数组。

Question

#include <stdio.h>
void reverse(int *a,int length);
int main()
{
    
    int a[12]={1,2,3,4,5,6,7,8,9,10,11,12,};
    reverse(a,12);
}
void reverse(int *a,int length)
{
    int i;
    for (i=0; i<length/2; i++) {
        int temp;
        temp = a[i];
        a[i]=a[length-i];
        a[length-i]=temp;
    }
    for (i=0; i<length; i++) {
        printf("%d ",a[i]);
    }
}

请帮忙看一下代码错在哪了，谢谢

第16 17 行，修改，供参考：

#include <stdio.h>
void reverse(int *a,int length);
int main()
{
    int a[12]={1,2,3,4,5,6,7,8,9,10,11,12,};
    reverse(a,12);
    system("pause");
    return 0;
}
void reverse(int *a,int length)
{
    int i;
    for (i=0; i<length/2; i++) {
        int temp;
        temp = a[i];
        a[i]=a[length-i-1];// a[i]=a[length-i];
        a[length-i-1]=temp;//a[length-i]=temp;
    }
    for (i=0; i<length; i++) {
        printf("%d ",a[i]);
    }
}
