It is also known that weak passwords are prone to brute force and dictionary attacks and can fail, leading to unauthorized access into user accounts, compromising security. To improve upon the robustness of the password chosen by a user, certain guidelines or requirements can be framed. Write a C++ program that accepts a user suggestion/choice of a password and checks if the chosen password satisfies the following requirements. The password contains: . at least 8 characters . at least one letter from the alphabet . • at least one decimal digit . at least one of the special characters: !, #, &, -, %, or @ The program displays an error message if all the conditions are not met.
