Question

Answer 1

#include <stdio.h>
int main()
{
    int n;
    scanf("%d", &n);
    int i, j;
    for (i = 1; i <= (n + 1) / 2; i++)
    {
        for (j = 1; j <= (n + 1) / 2 - i; j++)
        {
            printf("  "); //两个空格
        }
        for (j = 1; j <= i * 2 - 1; j++)
        {
            printf("* ");
        }
        printf("\n");
    }
    for (i = 1; i <= n / 2; i++)
    {
        for (j = 1; j <= i; j++)
        {
            printf("  ");
        }
        for (j = 0; j < n - i * 2; j++)// j与i成反比时，考虑-i，即相反数
        { 
            printf("* ");
        }
        printf("\n");
    }

    return 0;
