Hi. I have questions.

```auto
function abc()
{
  if(ab > varA) // 1
   {...;}

  if(ab <= varA) // 2
   {...;
     if(b) // 3
      {......;}
     if(c) // 4
      {.....;}
   }
  else
   {.....;
   }
}

```

Q1. in the above code, what is else’s counterpart? (1,2,3,4)

Q2. As you can see, variable ab is covered completely already before else statement.

Then, when the else statement work?

1. 

else works if ab \<= varA is NOT true, so it works when ab \> varA.

And this case is already the case 1. The else has no reason to exist.

To clarify further, the else-statement cannot stand on its own. It needs to be immediately after an if statement. The reason being is that the else-statement gets executed only if the condition of the if-statement before it is false. In this case the only thing that can make “ab \<= varA” false is “ab \> varA” which is covered already in your abc function clearly making it redundant code.

Thanks all.

I also suspicious why that else exist.

But the code if from my temporary programming teacher, so that I confused.

I also can’t question to him because I learned by video.
