这个就是一个初级课程的作业，你这个大师傅还猜不出来吗
 我下面还有一个问题 帮我看下：
打印出最大的3个值，我做到这里做不出来了

                  int a , b=0;
                  int max= 0 ;
                  int arr [10]= {1,2,3,4,5,6,7,8,9,10};
            
                   for (a=0; a < 10 ; a ++)
                   {
                       if (arr[a]>max)
                       {
                           max= arr[a] ;         
                          
                       }
                            if (arr[a]>max)                if (b<max&& b > arr[a]) 这里我用两种方法都打印不出来
                        {
                             b =max - 1 ;
                        }

                   }
                     printf("max =%d \n",max );
                     printf("b =%d\n",b);

  打印出最大的三个值，我用了好几种方法了 都打印不出来。


        
          int a , b , c;
                  int max= 0 ;
                  int arr [10]= {1,2,3,4,5,6,7,8,9,10};
            
                   for (a=0; a < 10 ; a ++)
                   {
                       if (arr[a]>max)
                       {
                           max= arr[a] ;         
                          
                       }
                       for (b = 0 ; b < 10 ; b ++)
                       {
                            if (b<max )
                        {
                             b =arr[b] ;
                        }
                       }

                   }
                     printf("max =%d \n",max );
                     printf("b =%d\n",b);
                        

                  int a , b , c;
                  int max = 0 ;
                  
                  int arr [10]={1,2,3,4,5,6,7,8,9,10} ;
            
                   for (a=0; a < 10 ; a ++)
                   {
                       if (arr[a]>max)
                       {
                           max= arr[a] ;                  
                       }            
                   }
                   printf("max =%d \n",max );
                    
                   for (b = 0 ; b < 10 ; b ++)
                   {
                        if (arr[b] > max)
                        {
                            max = arr[b]  ;
                        }
                   }
                   printf(" b  =%d \n" ,max-1 ); 这样可以不

标记下标跳过标记的下标，和降序排列，我都不太懂 。。。

哥，感觉你说的每句话都好有学问。
 我在自学，自学好难

在for 里面对数组清零， while循环里面 嵌套for ， 还有j = 3 这种我都没见过，，

先别睡，好人做到底呀， 代码看不懂，加个注释可以吗

呃呃呃， 你说的C语言才 30几个关键字是什么意思

打印质数，a%b进行求余，从2开始循环，如果余数为1，这个数是不是就是质数？
