5. Write a program that will ask the user to input a letter 'm' or 'f and then it will display "Hello Sir" if the input is 'm' otherwise, "Hello Madam".

Create a program that allows the user to enter a person's age (in years) and current salary. Both Next, you plan the algorithm and then desk-check it. Figure 8-15 shows the completed IPO algorithm contains two loops. The outer loop keeps track of the three annual raise rates (3%, 4%, chart and desk-check table, which (for simplicity) uses an age of 62 and a salary of $25000. The before retirement at age 65, using annual raise rates of 3%, 4%, and 5%. To calculate then for the input. In this case, the program should display a person's total earnings in Figure 8-15. You begin by analyzing the problem, looking first for the output and In this lab, you will plan and create an algorithm for the problem specification shown Frepure 8-15 Problem specification, IPO chart, and desk-check table for the retirement algorithm (continues) and 5%). The nested loop keeps track of the number of years until retirement. the amounts, the program will need to know the person's age and current salary. The…

3. Having a secure password is a very important practice, when much of our information is stored online. Write a program that validates a new password, following these rules: The password must be at least 8 characters long. The password must have at least one uppercase and one lowercase letter. The password must have at least one digit. Write a program that asks for a password, then asks again to confirm it. If the passwords don't match or the rules are not fulfilled, prompt again.
