what does code block mean?

That is the question: Say you had a conditional statement with one if clause, two else if clauses and an else clause, each with its own code block. What is the maximum number of code blocks in that conditional statement that can run?

My guess would be 4, but the answer is one.

......if(){ code block }else if (){ code block }else if(){ code block }else (){ code block }

Isn't that the way to calculate?

The code blocks are the statements within braces, just like you show.

And in this example, there are indeed 4 code blocks. But no matter how many code blocks you have in an if..else if... chain, only one of them can actually run β€” because all of the previous conditions would have been false, and none of the following conditions will be tested.
