language is c++ Lab12B: PasswordThis next problem is going to deal with checking if someone inputs a string with a few requirements.Imagine you are prompted to input a password, but the password needs to include uppercase lettersand a number. In order to do this, you must look at each char in the string and use Booleans to indicatecertain criteria are met. Since there are 3 criteria, you should have 3 Boolean variables.The rules for the password are:• Must contain at least 8 chars• Must contain 1 uppercase letter• Must contain 1 digit• There are no restrictions involving lowercase letters or special charsWhen considering where to use Booleans, think of it as a "flag", for each criteria. If you meet thelength requirement, then the flag would change from FALSE to TRUE. Once all the flags are true, youwill have a valid password.Tip: The ASCII table can be used to determine the numeric value of a particular char. You may wantto create ranges of these numerical values for each criteria.Sample output #1:Enter a password: passwordlInvalid passwordProgram EndsSample output #2:Enter a password: P4ssw3rdValid passwordProgram EndsSample output #3:Enter a password: Pas1Invalid passwordProgram EndsSample output #4:Enter a password: PASSwordInvalid passwordProgram EndsSample output #5:Enter a password: Pas!w3rdValid passwordProgram Ends
