Passing a 2 dimensional array to a Function

[poojithareddy]

Hai,
I am trying to pass a 2 dimensional array to a function and I am having
a problem with this.
If the array was a Static 2D array, the code would be somethinlike this

void displayArray(myArray[][10],int rowSize)

If it is a Dynamic array, the number 10 for the second dimension cannot
be mentioned and I dont know a workaround. Please let me know asap.

Thank You,
Poojitha.

Normally this

void displayArray(int **myArray, int rowSize, int colSize)

but really it depends on how you have created your 2D dynamic array. Why
not post the code you have written.

Your function would look something like this:

void displayArray(int** array, int numCols, int numRows);

you just tell it how many rows and columns are in the array.

Use 'vector<vector<whatever> >'

C++ does not have a core language data type, which would immediately represent a
2D array with flexible second dimension. This means that in order to represent
your 2D array you must be using a library- or user-defined data structure. The
answer to your question heavily depends on what you are actually using. Post
more details.

under NO circumstances use 'vector<vector<whatever> >'
but rather 'vector<vector<whatever> >& '
