What does “Comparing constant with boolean expression is always true” warning mean?

Question

What does this warning mean (i and j are not constants):

I have been trying to Google this but it does not give me any results.

Answer 1

I believe you need to understand what's going on in your statement at a deeper level.

0<=i is a boolean expression, it will become true or false. The result of that expression is then compared with 10.

So you end up with true <= 10 or false <= 10.

I think you meant to write

if ( ( 0 <= i ) && ( i <= 10 ) )

You cannot connect clauses together the way you did.
