nput:

Prompt the user to enter the desired length of the password within the range of $12$ to $16$ characters.

Generation:

Generate a password based on the specified length and complexity criteria. The password should be a

combination of uppercase letters, lowercase letters, digits, and special characters. Each character in the

password should be randomly generated. You might want to look into srand$()$ and rand$()$

functions in C$++$ on how to randomly generate a different character on each run of the program.

Output:

Display the generated password or prompt the user to retry if the password does not meet the criteria.

Below is the sample output of the program:

$$ If length is valid

$$ If length is not valid
