列印如上菱形。
基本思路,就是列印兩個三角形。一個朝上的等要三角形和一個朝下的等腰三角形,組合起來就是菱形。
代碼:
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace ConsoleApplication1{ class Program { static void Main(string[] args) { string str1 = ""; string str2 = ""; for (int i = 1; i <= 4; i++) { string s1 = ""; string s2 = ""; for (int j = 4 - i; j > 0; j--) { Console.Write(" "); s1 = s1 + " "; } for (int k = 1; k <= i * 2 - 1; k++) { Console.Write("*"); s2 += "*"; } str1 = s1 + s2; Console.Write("\n"); } for (int x = 1; x <= 3; x++) { string s3 = ""; string s4 = ""; for (int y = 1; y <=x ; y++) { Console.Write(" "); s3 += " "; } for (int z = 7 - x * 2; z >= 1; z--) { Console.Write("*"); } s4 += "*"; str2 = s3 + s4; Console.Write("\n"); } Console.ReadLine(); } }}
