c++如何将二维数组元素逆序储存

Question

比如a[3][3]={{1,2,3},{4,5,6},{7,8,9}}换成
a[3][3]={{9,8,7},{6,5,4},{3,2,1}}

Answer 1

 #include <stdio.h>

void chage(int array[], int n)
{
    int tem;
    for (int i = 0; i < n/2; i++)
    {
        tem = array[i];
        array[i] = array[n-1-i];
        array[n-1-i] = tem;
    }
}

int main()
{
    int a[] = {0,1,2,3,4,5,6,7,8,9};
    chage(a, 10);
    for (int i = 0; i < 10; i++)
        printf("%d ", a[i]);
    printf("\n");
}
