1.2       bowersj2    1: \label{Spreadsheet_Ternary_Operator}
1.3     ! bowersj2    2: The ?\index{? :}'s and :'s seen in the spreadsheet cells are part of
        !             3: compact notation for an if-then-else clause. Something like:
1.1       bowersj2    4: 
                      5: \texttt{( B2 > 16 ? 'passing grade' : 'failing grade')}
                      6: 
                      7: can be translated into:
                      8: 
                      9: \texttt{if (B2 > 16 ) \{ \\
                     10:   \hspace*{16pt}     \$temp = 'passing grade';\\
                     11:   \} else \{ \\
                     12:   \hspace*{16pt}     \$temp = 'failing grade'; \\
                     13:   \} \\
                     14:   \$temp;\\
                     15: }
                     16: 
1.2       bowersj2   17: The nicest part of the \texttt{( ? : )} operator (aside from its
                     18: compactness) is the way it automatically returns the value you want
                     19: without having to use any temporary variables.
