Declaration of pointer to array of pointers

Question

How can I declare 20 times

int p[] = { 1,2,3,4,5};
int p[] = { 6,7,8,9,10};
.
.
.

Let's say i have a matrix 20x20. each row is a pointer above

You can do this using a 20X20 2-dimensional array.

int p[][]={{1,2,3,4,5},
           {6,7,8,9,10},
           {11,12,13,14,15},
           .....
           .....
          }

EDIT: you can refer to the fifth row using this:

for(int i=0; i<5; i++)
{
   printf(" %d",p[4][i]);
}

But how will i refer to ( lets say row number 5 ) later?

you can refer to row number 5 using p[4].

syntax error.. it refers to the second [] in p[][] declaration
