Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Question

Learning objective: Make a decision based on 2 conditions both being true using the && operator.
Class to edit: Exercise6
Write a user login program that asks the user to input a username and then a password. If the
username equals "joe" and the password equals "guess", your program should accept this as
the correct login and print the message "Welcome, joe!". Otherwise your program should print
the message "Incorrect username or password.".
The following sample VO shows how your program should behave when both the username and
password are correct
Username: << user inputs joe >>
Password: << user inputs guess >>
Welcome, joe!!
Otherwise, your program should behave as follows:
Username: « user inputs joe >>
Password: << user inputs secret >>
Incorrect username or password.

99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.
public setUpTrip(double, double): void Car's state is set to hold the speed of travel and distance to travel at that speed Precondition: none Postcondition: Car's state holds information on distance to travel and speed to travel Parameters: Average Speed to be driven, Distance to drive Develop and use an algorithm that calculates the amount of fuel used and the actual distance driven in the drive() method. The algorithm must use a formula that gives proportionately poorer mileage when the Car is driven faster or slower than its optimal speed. When a new Car object is instantiated, it is initialized with an optimal speed variable. Your fuel usage algorithm should set limits on how poor of MPG your car will get. You may add other methods and fields as needed. When a new Car object is created, the car’s odometer is set to a random number between 0.0 and 5.99, the car’s trip odometer is set to 0.0, its best fuel economy (MPG) is set to a random number between 15.0 and 54.99, its…

The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false
