    47   In this tutorial, we shall look at

    48 \begin{itemize}

    49 \item Using if/else blocks

    50 \item Using if/elif/else blocks

    51 \item Using the Ternary conditional statement

    58   Given a number, num. Write an if else block to print num, as is, if

    59   it is divisible by 10, else print 10 * num.

   107   In this tutorial session we learnt

   108 

   109 \begin{itemize}

   110 \item What are conditional statements

   111 \item if/else statement

   112 \item if/elif/else statement

   113 \item Ternary conditional statement - \texttt{C if X else Y}

   114 \item and the \texttt{pass} statement
