-Commonly, when solving a problem, we select among several choices depending on whether certain conditions are met. Computer programs are built to solve problems, so they should have a structure that allows them to make decisions and select alternatives. In C++ selections are structured using `if`, `else`, `else if` or `switch`. Relational expressions and logical operators are common when handling selection structures. In today's laboratory experience you will practice the use of some of these selection structures by completing the design of an application that determines the strength of a password.

 Since an official system to measure password strength doesn't exist, we will use formulas created by the passwordmeter to evaluate the general strength of a given password [1]. We recommend that you play around a bit with the application in http://passwordmeter.com so that you understand how the application you will be implementing should behave. The strength of the password will be quantified by adding points for using good techniques of password selection (like using symbols and letters), and subtracting points for using bad habits (like only using lowercase letters or consecutive symbols of the same type).
