The if statement
Before diving into some exercises on the if statement, have another look at its syntax:
if (condition) {
expr
}
Remember your vectors with social profile views? Let's look at it from another angle. The medium variable gives information about the social website; the num_views variable denotes the actual number of views that particular medium had on the last day of your recordings. Both variables have been pre-defined for you.
