Briefly describe how the and operator works

Write an if statement that assigns 0 to the variable b and assigns 1 to the variable c if the variable a is less than 10.

Write an if statement that checks if the value a lies in the range of 10 to 30 and assigns the value of the variable a to 20.

Write a program that asks the user to enter a number of seconds, and works as follows:

• There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes in that many seconds.
• There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours in that many seconds.
• There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days in that many seconds.

You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements. What structure will you use?

The __________ statement causes one or more statements to execute only when a Boolean expression is __________. a. else, false b. if, true c. if, false d. else, true

A__________ structure provides one alternative path of execution.
a. sequence
b. single alternative decision
c. one path alternative
d. single execution decision

A program can be made of only one type of control structure. You cannot combine structures.

Give an example of a nested if-else statement.

The area of a rectangle is the rectangle's length times its width. Write a program that asks for the length and width of two rectangles. The program should tell the user which rectangle has the greater area, or if the areas are the same.

Enhance the hit_the_target.py program so that, when the projectile misses the target, it displays hints to the user indicating whether the angle and/or the force value should be increased or decreased. For example, the program should display messages such as 'Try a greater angle' and 'Use less force.'

You have a group of friends coming to visit for your high school reunion, and you want to take them out to eat at a local restaurant. You aren't sure if any of them have dietary restrictions, but your restaurant choices are as follows:

Joe's Gourmet Burgers_Vegetarian: No, Vegan: No, Gluten-Free: No
Main Street Pizza Company-Vegetarian: Yes, Vegan: No, Gluten-Free: Yes
Corner Café-Vegetarian: Yes, Vegan: Yes, Gluten-Free: Yes
Mama's Fine Italian-Vegetarian: Yes, Vegan: No, Gluten-Free: No
The Chef's Kitchen-Vegetarian: Yes, Vegan: Yes, Gluten-Free: Yes

Write a program that asks whether any members of your party are vegetarian, vegan, or gluten-free, to which then displays only the restaurants to which you may take the group. Here is an example of the program's output:

Is anyone in your party a vegetarian? yes <Enter>
Is anyone in your party a vegan? no <Enter>
Is anyone in your party gluten-free? yes <Enter>
Here are your restaurant choices:
    Main Street Pizza Company
    Corner Cafe
    The Chef's Kitchen

Here is another example of the program's output:

Is anyone in your party a vegetarian? yes <Enter>
Is anyone in your party a vegan? yes <Enter>
Is anyone in your party gluten-free? yes <Enter>
Here are your restaurant choices:
    Corner Cafe
    The Chef's Kitchen

The month of February normally has 28 days. But if it is a leap year, February has 29 days. Write a program that asks the user to enter a year. The program should then display the number of days in February that year. Use the following criteria to identify leap years:

1. Determine whether the year is divisible by 100 . If it is, then it is a leap year if and only if it is also divisible by 400 . For example, 2000 is a leap year, but 2100 is not.
2. If the year is not divisible by 100 , then it is a leap year if and only if it is divisible by 4. For example, 2008 is a leap year, but 2009 is not.

Here is a sample run of the program:

Enter a year: 2008 <Enter>`
In 2008 February has 29 days.

A____________ is a Boolean variable that signals when some condition exists in the program.
a. flag
b. signal
c. sentinel
d. siren
