int funcZ( int array[][], int k, int b,int  c )

{
... .. .. ..
Funcb(array[x][], k, b);
Funcb(array[][x], k, c);
...

}

int Funcb(int arr[], int k, int d )
{
....
}

b is binary search, but according to my code, array[][]'s first []'s search then other []'s search.. so of course it can not be compiled, how to correct it..

hi

what you want to do simply can not be done
for c, an [] specification means a contiguoes memory that holds x items of the same data type
when you specify [][x], the space you are refering to is not contiguoes, and the compiler can not treat it as a reguler [] type,

what you can do is create a [] from the data and then pass it to the function, for exapmle :
Funcb(array[x][], k, b);

int temp[];
int i;

for (i=0; i<array_size; ++i) {
   temp[i] = array[i][x];
}

Funcb(temp, k, c);

Do you want to do something with 2D array rows and columns? In this case try the following function:

int Funcb(int* arr,     /* pointer to first array member/*
     int step,               /* distance between members/*
     int size,               /* number of elements to handle*/
     int k, int d )         /* your existing parameters - I don't know what they are */
{
    int i;

    for ( i = 0; i < size; i++ )
    {
         // work with *arr
         // move to next element: increment arr to step
    }
}

For example, you have 10*10 array. To handle array row, call Funcb with step = 1. To handle array column, call Funcb with step = 10.

Correction:
To handle array column, call Funcb with step = 9.
