Using the string class, design and develop a multi-file password validation program and test case document (10% of grade) that requests a password, and validates it based on the following criteria.

the password must be at least 8 characters long, contain at least one number, and at least one upper case letter, and at least one lower case letter.
the user is limited to three (3) attempts and then is locked out and the program ends.
required functions called from main and located in a header file: prompt for and getting input, validating the password, re-entry (confirming), and output. the main loop can be in main.

1. request a password from the user
2. test to see if the password entered is valid (length, upper case, lower case, digit) if the password is not valid
i. output the original password entered
ii. output that it is not a valid password
iii. output each of the reasons why the password is not valid

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
