同学复试的一道C语言题目

n×n的矩阵，采用顺时针打印出1~16.

 

#include <stdio.h>

#define MATRIX 4

static int data[4][4] = {{1, 2, 3, 4},
            {12, 13, 14, 5},
            {11, 16, 15, 6},
            {10, 9, 8 ,7}
            };
int main()
{
    int n, i, j, l;

    for (n = MATRIX; n > MATRIX - 2; n--) {
        for (i = j = MATRIX - n; j < n - 1; j++)
            printf("%d", data[i][j]);
    　　 for (i = MATRIX - n; i < n - 1; i++)
            printf("%d", data[i][j]);
        l = i;
        for (j = l; j > MATRIX - n; j--)
            printf("%d", data[i][j]);
        for (i = l; i > MATRIX - n; i--)
            printf("%d", data[i][j]);        
    }
    putchar('\n');
    return 0;
}
