Returning Number of Rows and Colums in a 2-D array in C

[hefty1985]

Dear all,

I hope you can help. Is any one aware of a function that would return the number of Rows and Columns of a 2-D array in C ( Matrix)?

Or, how to go about writting a function with the Matrix as an input array and numbers of the matrix rows and columns (Similar to SIZE( ) function in MATLAB) as outputs.

Best regards,

I don't understand your question, when you declare a 2D array you specify the number of rows and columns.

int array[10][12]

why do you need to determine the size if you already know it?

Hi,

In case a 2-D array is to be passed to as an input to a function who declares this input parameter as a pointer. IS there a way that this function can realise the 2-D dimensions i.e. number of row and columns.

No, you either have to pass the width and height as parameters or if you are using C++ then you could create a class for ayour matrix and pass references to matrix objects which would know their own height and width.

Is this a homework assignment? It sounds suspiciously like another post in this forum.
