I paid 80€ for an iPad sleeve that breaks down after 1 year in my backpack. Enough said.

I think the main advantages over C are:

• better tooling
• modern syntax
• by default, pointers must be non-null. You have to specify if you want to use null pointers
• better exception handling using the functional style of exceptions-as-values

There are probably more, but those are the ones I remember.
