I was doing the Conditionals Quiz in iOS Development with Objective-C and not pass this question.

When utilizing conditional statements in Objective-C that will account for more than 2 possible conditions, you can either use If-Else statements or Switch statements. The question on that quiz is referring to the use of the If-Else conditional statements.

1. The general rule of thumb is that the first statement with a specific condition is written as an 'If' statement.
2. Every other statement with a specific condition is written as an 'Else-If' statement.
3. The last statement (that will usually refer to the condition that no other of your aforementioned conditions are fulfilled) is written as an 'Else' statement. Therefore, in the question, the completed conditional statement will look like this:

if ( i < 0 ){ printf("negative")
} 
else if ( i > 0 ) {
printf("positive");
} 
else {
printf("zero"); }
