Understanding c-pointers for rows in 2-dimensional array
- by utdiscant
I have the following code:
int main() {
int n = 3, m = 4, a[n][m], i, j, (* p)[m] = a;
for (i = 0; i < n; i++)
for (j = 0; j < m; j++)
a[i][j] = 1;
p++;
(*p)[2] = 9;
return 0;
}
I have a hard time understanding what p is here, and the consequences of the operations on p in the end. Can someone give me a brief explanation of what happens. I know c-pointers in their simple settings, but here it get slightly more complicated.
