c/c++语言开发共享C语言：在二维数组中，每行每列都按照递增的顺序排序，判断数组中是否包含一个数。

  #define _crt_secure_no_warnings 1  #include<stdio.h>  #include<stdlib.h>  int search_target(int arr[], int target, int row, int column)  {   int row = 0;   int column = column - 1;   if (arr != null && row > 0 && column > 0)   {    while (row < row && column >= 0)    {     if (arr[row * column + column] == target)     {      return 1;     }     else if (arr[row * column + column] < target)     {      ++row;     }     else if (arr[row * column + column] > target)     {      --column;     }    }    return 0;   }   return 0;  }  int main()  {   int arr[][3] = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };   int ret = search_target(arr, 7, 3, 3);   if (ret == 1)   {    printf("existn");   }   else   {    printf("not existn");   }   system("pause");   return 0;  }
