Format String Vulnerabilities: These occur when untrusted input is used as the format string in a formatted output function. This can allow an attacker to read or write arbitrary memory, leading to a security vulnerability. While this is more common with the printf family of functions, it can also occur with iostream if care is not taken. *Can you provide a simple iostream example of a format string vulnerability? How do you correct this vunlerability?*

Focus on string operations and methods You work for a small company that keeps the following information about its clients: • first name • last name • a 5-digit user code assigned by your company. The information is stored in a file clients.txt with the information for each client on one line (last name first), with commas between the parts. For example Jones, Sally,00345 Lin ,Nenya,00548 Fule,A,00000 Smythe , Mary Ann , 00012   Your job is to create a program assign usernames for a login system. First: write a function named get_parts(string) that will that will receive as its arguments a string with the client data for one client, for example “Lin ,Nenya,00548”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and newlines from the end of the parts. You’ll need to use some of the string methods that we covered in this lesson You can test your function by with a main() that is just the function call with the…

createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).
