Answer 1

The for loop doesn't do anything. Note the empty curly brackets. It's an empty statement, just like for(int i = 0;i<7;++i); // <= note the semicolon at the end. Also, the variable i in the for loop is not the same variable that is used outside of the loop, because it was declared in the for loop. So the outer variable i isn't affected in any way.

If you change it like this:

for(i=0; i<7; ++i) {}

it will actually affect the outer variable i.

Answer 2

5, because loop is not for i
