Hello everybody,(Hello Tyler)

Well, some days ago, i was asking about how to define a bidimensional
dynamic array as a global variable to use as incoming variable in a
function, but i could not solve the problem.

Let us see , for example in a part of a programm my problem:

#include<iostream>
...
using namespace std;

float a[10][10];//in this place i wish define a bidimenional dynamic array
agian: how to do it?
...
//follow the function 

float suma(int k, float a[][10])
 {
   float s=0;
   for (int i=1;i<k;i++)
     for (int j =1;j<k;j++)
       s=s+a[i][j];
   return (s);
}

int main()
{ 
  ...
  suma(k,a);
...
}

But instead defining an static bidimensional array a[10][10], to use after
as an incoming variable in a function, i wish to define it as dynamic
array(to work with  a huge array for example(a[500][500]) )

would you like to help me?
