Is That scanf is working fine..?
Working only after some changes, for me..
I found 2 mistakes..
May be works in system without changes in scanf derective

Answer 2

With the array size, I think no problem, because he accessing upto m=2,n=2.
But he is when not given the value to p<m.
So segment error..
And taking input <m, but accessing <=m, so extra garbage values...
For the sf derective, not working to take inputs... Changed to

#define sf(x, y) scanf(x, y)
p=0;
i<m; //not i<=m; in last for loop, else m=p+m;

I made these chages, then working fine...

Yes. But you are not making it sure that p+1=m, anywhere. So
If you give p value other than 1, It leading to overflow...

Is that sf derective working fine you there?

Now, Only make sure p<m, otherwise it cause overflow...
Remaining all Working fine..
