Answer 5

我也来写个，C＃版的：
namespace ConsoleApplication6
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i < 7; i++)
            {
                for (int j = 0; j < i; j++)
                {
                    Console.Write("*");
                    for (int k = 1; k < i; k++)
                        Console.Write(".");
                }
                Console.WriteLine();
            }
        }
    }
}

Answer 6

public class Test5 { public static void main(String[] args){

for(int i = 0; i < 7; i++){
if( i == 5){
for(int j = 0; j < 13; j++){
System.out.print("*");
for(int k = 0; k < i; k++)
System.out.print(".");
}
}
else{
for(int j = 0; j < i; j++){
System.out.print("*");
for(int k = 0; k < i; k++)
System.out.print(".");
}
}
System.out.println("");
}
}
}

Answer 7

如果三层循环的外层条件a<100、a<1000怎么办啊，电脑会炸吗？

接近最佳解了。哈哈，速度最快，效率最好。可以考虑直接输出一次，不要这么多System.out.println();哈哈

Answer 13

Answer 15

又修改了下，勉强解决问题。.^_^.
public class TestPrint
{//要打印的次数
   private static int LEN = 7;
   //递归打印单行
   private static void printStr(int len , int num)
   {
     System.out.print("*");
     num++;
     if ( num >= len)
     {
     printOther( len - 1 , 0);
     System.out.println("");
     return;
     }
     else
     {         
     printOther( len - 1 , 0);
     printStr( len , num);
     }
    
    }
    //打印*号
    private static void printOther( int len ,int num)
    {    
     num++;
     if ( num > len)
     {
     return ;
     }
     else
     {
     System.out.print(".");
     printOther( len , num);
     }
    }
    //主程序，循环打印每行
    public static void main(String[] args)
    {
for ( int i = 1 ; i < LEN + 1 ; i ++ )
{
printStr ( i , 0);
}         
    }
}

Answer 16

狂顶，这题真强啊，要三循环，看起来很简单，但是做起来很不简单啊。public static void main(String[] args) {
for (int a = 1; a < 7; a++) {
for (int b = 0; b < a; b++) {
System.out.print("*");
for (int c = 1; c < a; c++) {
System.out.print(".");
}
}
System.out.println();
}
}

Answer 17

考官没水平，出来问有水平！ 二楼更有水平。
