我有一本书的示例程序，在这段代码中有一行
++frequency[responses[RESPOSE_SIZE]];。我无法理解我们如何增加数组基地址？也许我是个傻瓜？但我仍然看不到那里的任何逻辑...请有人帮我....谢谢！

    int main()
    {
          int answer, rating;

           int frequency[FREQUENCY_SIZE] = {5};

           int responses[RESPOSE_SIZE] ={1,2,3,4,5,6,7,8,9,10,

                1,6,3,8,6,10,3,8,2,7,6,5,7,6,8,6,7,5,6,6,

                5,6,7,5,6,4,8,6,8,10};

       for(answer = 0; answer<RESPOSE_SIZE; answer++)
       {

          ++frequency[responses[RESPOSE_SIZE]];
       }

       printf( "%s%17s\n", "Rating", "Frequency" );

       for(rating=1; rating<FREQUENCY_SIZE; rating++)
       {
          printf( "%6d%17d\n", rating, frequency[ rating ] );

       }

        return 0;
    }

最佳答案

++frequency[responses[RESPOSE_SIZE]]并不意味着该数组的基地址增加。

这意味着数组frequency中从位置responses[RESPONSE_SIZE]开始的项目将递增。构造responses[RESPONSE_SIZE]是数组responses中位于位置RESPONSE_SIZE的项。
