-C++ Code Vulnerabilities-

Looking for formatted output vulnerabilities in the code posted below or where this code avoided possible formatted output problems. Looking for three or more answers corresponding to this code and vulnerabilities having to do with formatting input and output errors and some explanation of what those vulnerabilities are and how to solve/avoid them. Thanks!
