Draw Christmas Tree in C: Complete Code Tutorial

Here is a simple sample code in C language to draw a Christmas tree.

#include <stdio.h>

int main() {
    int i, j, k;
    int rows = 10; // 圣诞树的行数

    for (i = 0; i < rows; i++) {
        for (j = 0; j < rows - i - 1; j++) {
            printf(" "); // 打印空格
        }

        for (k = 0; k < 2*i + 1; k++) {
            printf("*"); // 打印圣诞树的主干
        }

        printf("\n");
    }

    for (i = 0; i < 3; i++) {
        for (j = 0; j < rows - 2; j++) {
            printf(" "); // 打印空格
        }

        for (k = 0; k < 5; k++) {
            printf("*"); // 打印圣诞树的树梢
        }

        printf("\n");
    }

    return 0;
}

This code will print a simple Christmas tree shape, and you can adjust the value of rows as needed to control the size of the Christmas tree.
