编写嵌入的for循环

Question

（输入一个数字金字塔图案）编写一个嵌入的for循环，输出下面的图案

Answer 1

#include <stdio.h>

int main() {
    int num, rows, i, j, space;

    printf("请输入行数：");
    scanf("%d", &rows);

    space = rows;

    for (i = 1; i <= rows; i++) {
        for (j = 1; j <= space; j++) {
            printf("  ");
        }
        space--;

        int current = 1;

        for (j = 1; j <= i; j++) {
            printf("%d ", current);
            current *= 2;
        }

        current /= 2;

        for (j = i-1; j >= 1; j--) {
            current /= 2;
            printf("%d ", current);
        }

        printf("\n");
    }

    return 0;
}

运行结果如下：
