C# 打印星號菱形

代碼如下

 

                       Console.Write( 
          " 
          請輸入要打印的行數(奇數): 
          "); 
          
             
          int n =  
          int.Parse(Console.ReadLine()) /  
          2 +  
          1;  
          // 
          這樣就算出上部分的總行數了 
          
 
          
             
          for ( 
          int i =  
          1; i <= n; i++) 
          
            { 
          
                 
          for ( 
          int j =  
          1; j <= n - i; j++) 
          
                { 
          
                    Console.Write( 
          " 
            
          "); 
          
                } 
          
                 
          for ( 
          int k =  
          1; k <=  
          2 * i -  
          1; k++) 
          
                { 
          
                    Console.Write( 
          " 
          * 
          "); 
          
                } 
          
                Console.WriteLine(); 
          
            } 
          
 
          
             
          for ( 
          int i =  
          1; i < n; i++) 
          
            { 
          
                 
          for ( 
          int j =  
          1; j <= i; j++) 
          
                { 
          
                    Console.Write( 
          " 
            
          "); 
          
                } 
          
                 
          for ( 
          int k =  
          1; k <= ( 
          2 * n -  
          1) -  
          2 * i; k++) 
          
                { 
          
                    Console.Write( 
          " 
          * 
          "); 
          
                } 
          
                Console.WriteLine(); 
          
            }
