Question

C#实验，输出菱形，用循环语句写，跪求代码

Answer 1

console？

int h=10;
for(int i=1;i<=h;i++)
{
       Console.WriteLine(“”.padleft(i,'*'));

｝
for(int i=h-1;i>0;i--)
{
       Console.WriteLine(“”.padleft(i,'*'));
}

Answer 2

static void Function3()
{
for (int i = 0; i < 5; i++)
{
for (int j = 0; j <= 4-i; j++)
{
Console.Write(" ");
}
for (int l = 0; l < i * 2 + 1; l++)
{
Console.Write("*");
}
Console.WriteLine();
}
for (int i = 0; i < 5; i++)
{
for (int k = 0; k <= i+1; k++)
{
Console.Write(" ");
}
for (int u = 0; u < 7 - i*2; u++)
{
Console.Write("*");
}
Console.WriteLine();
}
}

Answer 3

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int a, i;//a是总行数，i用来控制行数小于总行数，j用来控制每行的*和空格的输出。
            Console.Write("请输入菱形总行数：");
            a = Convert.ToInt32(Console.ReadLine());
 
            if (a % 2 == 0)
            {
                Console.Write("输入错误，请输入奇数:");
                a = Convert.ToInt32(Console.ReadLine());
            }
            else
            {
 
                for (i = 1; i <= a; i++)
                {
                    if (i <= (a + 1) / 2)
                    {
                        for (int j = 0; j < (a + 1) / 2 - i; j++)
                        {
                            Console.Write(" ");
                        }
                        for (int j = 0; j < i; j++)
                        {
                            Console.Write("* ");
                        }
                        Console.WriteLine();
                    }
                    else
                    {
                        for (int j = 0; j < i - (a + 1) / 2; j++)
                        {
                            Console.Write(" ");
                        }
                        for (int j = 0; j < a + 1 - i; j++)
                        {
                            Console.Write("* ");
                        }
                        Console.WriteLine();
                    }
                }
                Console.ReadLine();
            }
        }
    }
}

偶数是不可以哦，必须是奇数
