五阶魔方阵，对角线相加的c语言实现代码

下面是五阶魔方阵，对角线相加的 C 语言实现代码：

#include <stdio.h>

#define N 5

int main() {
    int magic_square[N][N] = {0};
    int row = N-1, col = N/2, i, j;
    int num = 1;

    // 将数字填入魔方阵中
    while (num <= N * N) {
        magic_square[row][col] = num++;
        int next_row = (row + 1) % N;
        int next_col = (col + 1) % N;
        if (magic_square[next_row][next_col] == 0) {
            row = next_row;
            col = next_col;
        } else {
            row = (row - 1 + N) % N;
        }
    }

    // 输出魔方阵并计算对角线之和
    int sum1 = 0, sum2 = 0;
    for (i = 0; i < N; i++) {
        for (j = 0; j < N; j++) {
            printf("%2d ", magic_square[i][j]);
            if (i == j) {
                sum1 += magic_square[i][j];
            }
            if (i + j == N-1) {
                sum2 += magic_square[i][j];
            }
        }
        printf("\n");
    }
    printf("Sum of diagonal 1: %d\n", sum1);
    printf("Sum of diagonal 2: %d\n", sum2);

    return 0;
}

该程序使用了一个 5x5 的二维数组 `magic_square` 存储魔方阵，然后通过遍历填入数字。同时，程序还计算了对角线之和，并输出结果。
