c语言动态圣诞树代码

以下是C语言动态圣诞树代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>

#define TREE_HEIGHT 20

int main() {
    int i, j, k;
    int tree_width = TREE_HEIGHT * 2 - 1;
    char tree[tree_width][TREE_HEIGHT];
    memset(tree, ' ', sizeof(tree));

    while (1) {
        for (i = 0; i < TREE_HEIGHT; i++) {
            for (j = 0; j < tree_width; j++) {
                if (j >= TREE_HEIGHT - i - 1 && j <= TREE_HEIGHT + i - 1) {
                    tree[j][i] = '*';
                }
            }
        }

        for (i = 0; i < TREE_HEIGHT; i++) {
            for (j = 0; j < tree_width; j++) {
                printf("%c", tree[j][i]);
            }
            printf("\n");
        }

        for (k = 0; k < TREE_HEIGHT / 2 k++) {
            printf("%*s||\n", TREE_HEIGHT, "");
        }

        usleep(500000);
        system("clear");

        memset(tree, ' ', sizeof(tree));
    }

    return 0;
}
