Negative result is also a result ;).

No. Stop. The bug crawling right here (honestly speaking, not right here but
in you comments and understanding. By declaration of massive:

BITMAP *ani1[5];

you declaring ONLY FIVE bitmaps in array -- from zero to four not including
five.

So, that string needs to be changed:
for (i=0; i<5; i++) {

Looks pretty nice.  Is it starting from -1?  Try to change it to 'i'.

And that too.

btw, Pascal was created for teaching structural priogramming and C was
created for implement it for the most effective way ;).

Ok, I will not as it is your license stuff :).
