Hi to all,
 
I assume that the given context asks for using C and not C++.
 
Who has to work with 2D, 3D arrays and subarrays in C on a 
regular basis may find the treatment of these topics in
Press, Teukolsky,Vetterling,Flannery: Numerical Recipes in C,
Cambridge University Press
useful.
 
Who is willing to switch to C++ is in paradise yet:
 
#include <vector>
using std::vector;
 
 
int main()
{
int i,,j,lin=3, col=4;
 
    vector< vector<int>  > vector2D(lin, vector<int>(col));
        // constructor call,  destruction is automatic
 
    for(i=0; i<lin;  i++)
for(j=0; j<col;  j++)
vector2D[i][j]  = i + j;
 
// what follows does not belong to the paradise I spoke about
 
    for(i=0; i<lin; i++){
for(j=0; j<col; j++){
printf("%d\t",  vector2D[i][j]);
}
printf("\n");
}
 
   system("PAUSE");
return 0;
}
