Some Web sites impose certain rules for passwords. Write a function that checkswhether a string is a valid password. Suppose the password rules are as follows:A password must have at least eight characters. A password must consist of only letters and digits. A password must contain at least two digits. Write a program that prompts the user to enter a password and displays validpassword if the rules are followed or invalid password otherwise.

Assume you need to test a function named inorder. the function inorder receives three int arguments and returns true if and only if the arguments are in non-decreasing order: that is, the second argument is not < the first and the third is not < the second. write the definition of driver function testinorder whose job it is to determine whether inorder is correct. so testinorder returns true if inorder is correct and returns false otherwise. for the purposes of this exercise, assume inorder is an expensive function call, so call it as few times as possible!
