How do I pass a 2D array in CVI and reference if in a function?

[ClutchProgrammer]

I am trying to write a function that selects values out of a 2D array.  I want to pass the array and then reference it later.  I have tried several ways the last being:

float table[10][10];

bool function(float *array);

main
{
     //Do work

    function(table);

    return;
}

bool function(float *array)
{
    float number = array[3][4];

    if (number > 0)
        return true;
    else
       return false;
}

I am used to programming in the c++ world but, this project requires I use cvi any suggestions?

You could always prototype it as: 

bool function (float [10] [10]);

 That way the compiler knows all it needs to, to successfully access the desired components.

Hi, you can find in this thread some useful informations about creating and using 2d arrays and functions that manipulates those arrays.

I have done that in the past but, in this case I have arrays of different sizes being passed into the same function. 

I forgot to add in my last post that when I use the above code I get an error of:

  572, 44  Type error: pointer expected.

Thanks Roberto. 

Now, that you mention it that does seem like the right way to do it.  Should have thought of that before.

Additionally, bool is not a type in C (and true and false are not built in constants); you could do something like

typedef int bool;

#ifndef TRUE
#define TRUE 1
#endif

#ifndef FALSE
#define FALSE 0
#endif

if you want. This is a fairly common idiom. Frequently, people use boolean instead of bool (mainly so the code will compile in C and C++ compilers).

Adding this along with changing the function prototype to

bool function (float array[10][10]);

in both places will make this code compile.

Hope this helps,
