Answer 1

*In very simple words

Because the loop don't have any block, the variable m is increased by 1, because there's a semicolon right after the m++ operation that's where the scope of that for loops ends.
So loop only works for variable m not for n.

that's it, hope you understood.

Answer 2

There are no {}. Only the m++ line is in the for loop. n++ runs only once.

Answer 3
