Question: What are the advantages of using cin and cout compared to scanf(...) and printf(...), respectively?

Answer: Compared to the standard C functions printf() and scanf(), the usage of the cin and cout is more type safe.
The format strings, which are used with printf() and scanf() can define wrong format specifies for their arguments, for which the compiler does not warn.
In contrast, argument checking with c in and cout is performed by the compiler.
C in and Cout are stream classes that could be used to receive and print objects respectively.
