The “write” member function: The “write” member function is one of the file stream object’s functions and it is used to write the binary data or raw data in the specified file. The syntax of the “write” function is as follows: filestreamobject.write(address,size) The “filestreamobject” is the object name of a stream. The argument “address” indicates the part of the memory that is to be written on the specified file. This argument must be address or pointer of a char. The argument “size” indicates the number of bytes which is to be written. This argument must be an integer. Typecast – Converts the value of one type into another type. The type cast which is used to convert the pointer of one type to another type is “reinterpret_cast”. The basic format for “reinterpret_cast” as follow as: reinterpret_cast <dataType>( argument) Here, the “dataType” is the type that user converting to, similarly the “argument” is the value which the user wants to convert.

Program Plan Intro

The “write” member function:

The “write” member function is one of the file stream object’s functions and it is used to write the binary data or raw data in the specified file.

The syntax of the “write” function is as follows:

filestreamobject.write(address,size)

The “filestreamobject” is the object name of a stream.

The argument “address” indicates the part of the memory that is to be written on the specified file. This argument must be address or pointer of a char.

The argument “size” indicates the number of bytes which is to be written. This argument must be an integer.

Typecast – Converts the value of one type into another type.

The type cast which is used to convert the pointer of one type to another type is “reinterpret_cast”.

The basic format for “reinterpret_cast” as follow as:

reinterpret_cast <dataType>( argument)

Here, the “dataType” is the type that user converting to, similarly the “argument” is the value which the user wants to convert.

Password validation Write a program password.py that reads a file containing multiple passwords and checks the validity of the passwords. The file format is identical to one of the sample passwords.txt provided below. Your program must contain the following functions: Function name Function description Function input(s) Function return value(s) validate() This function takes a password string as input and returns a boolean that determines if the password is valid or invalid. The requirements for a valid password are: The password must be at least 9 characters long and at most 18 characters long (included). The password must end with a letter. The ending letter must be uppercase. The password must contain `62` The password must not start with `@` The password must contain at least 4 digits Password string Boolean main() This function prompts for a file of passwords. Next, it opens the file. Next, it checks for the validity of every password in…
