I'm trying to use a multidimensional array (of pointers) as a function argument. However, I always get a 'dimension of array'-error when using an array with more than one dimension. here's a little example: one dimension (works)
#include <acknex.h>
var vars[8];
void print_var(var *input_array, unsigned int index_x)
{
var output_var = input_array[index_x];
printf("array[%.0f] = %.0f", (double)index_x, (double)output_var);
}
void main()
{
int i;
for(i = 0; i < 8; i++)
{
vars[i] = random(100);
}
print_var(vars, 3);
}
exactly the same using two dimensions (doesn't work)
#include <acknex.h>
var vars[8][8];
void print_var(var *input_array, unsigned int index_x, unsigned int index_y)
{
var output_var = input_array[index_x][index_y];
printf("array[%.0f][%.0f] = %.0f", (double)index_x, (double)index_y, (double)output_var);
}
void main()
{
int i;
for(i = 0; i < 8; i++)
{
int j;
for(j = 0; j < 8; i++)
{
vars[i][j] = random(100);
}
}
print_var(vars, 3, 5);
}
Does anybody know a solution to this problem?

Sorry, but could you please post a small example? edit:@Ch40zzC0d3r: if you mean changing this void print_var(var *input_array, unsigned int index_x)into this: void print_var(var **input_array, unsigned int index_x)I've tried that before, didn't work

void print_var(var input_array)
{
var output_var = input_array;
printf("%.0f", (double)output_var);
}

Please! Use easy words to be translated. because my English is not very good! Grateful.

OR:
void print_var(var **input_array, int index_x, int index_y)
{
var output_var = vars[index_x][index_y];
printf("array[%.0f][%.0f] = %.0f", (double)index_x, (double)index_y, (double)output_var);
}

NeoNeper: thanks, but that's not what I'm looking for.
The code I've posted should just show the problem I have.
Printing a var from an array is not exactly what I want to do.

Sorry if you misunderstood me but like I've said previously: this is not what I'm looking for.
in your example you're accessing the global array 'vars' in the function:
void print_var(var **input_array, unsigned int index_x, unsigned int index_y)
{
var output_var = vars[index_x][index_y];
however, I want to access it by using the array as a function argument.
void print_var(var **input_array, unsigned int index_x, unsigned int index_y)
{
var output_var = input_array[index_x][index_y];
