Variables declared but not initialized have the value of
a.null
b.0
c.undefined
d.empty
Step by step
Solved in 2 steps
- A(n) variable is one that has been declared, but has not been initialized or assigned avalue.a. undefinedb. uninitializedc. emptyd. defaultTrue or False You can declare multiple variables of different data types with one declaration.True or False: You cannot change the value of a variable whose declaration uses the final keyword.
- This value initializes the formula that generates random numbers.a. dummy valueb. random valuec. seed valued. new valuState true or false ; The result of a calculation made by an application should be stored in a variable.Savings Account The following steps calculate the balance after three years when $100 isdeposited in a savings account at 5% interest compounded annually:1. Declare the variable balance as type Decimal.2. Assign the value 100 to the variable balance.3. Increase the variable balance by 5% of its value. (Write 5% as 0.05D.)4. Increase the variable balance by 5% of its value.5. Increase the variable balance by 5% of its value.6. Display the value of balance (rounded to two decimal places) in a list box.
- By default, global variables are static variables. Select one: O True O False Next pag99 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.What is the benefit of being able to define an initial value when you can assign a value to a variable?
