- The cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.Fahrenheit to Celsius using multiple statements Given a Fahrenheit value temperatureFahrenheit, write a statement that assigns temperatureCelsius with the equivalent Celsius value. While the equation is C = 5/9 * (F - 32), as an exercise use two statements, the first of which is "fractionalMultiplier = 5/9:". Check if varlables temperatureFahrenheit, fractionalMultiplier, and temperatureCelsius exist Variable temperatureCelsius does not exist. From MatlabWrite multiple if statements. If car_year is 1969 or earlier, print "Few safety features." If 1970 or later, print "Probably has seat belts." If 1990 or later, print "Probably has antilock brakes." If 2000 or later, print "Probably has airbags." End each phrase with a period and a newline.

- 1. Prompt the user and read in the number of a team playing the current game, i.e. Team 1, Team 2, Team 3, etc. 2. Prompt the user and read in the number of the opponent team. It is probably helpful to think of the first team as the home team for this game, and the second team as the away team. 3. Prompt the user and read in a team’s score for the current game. Use the team’s number when asking for the score in your printf statement. 4. Prompt the user and read in the opponent’s score for that game. Again, use the opponent’s team number when asking for the score. 5. Notify the user and repeat steps 3 and 4 in the case that the user enters a negative value. 6. Calculate the points earned by each team and add it to a cumulative score. A win is worth 3 points, a draw is worth 1 point and a loss is zero points. Also update the amount of games played by each team and their goals for and against. 7. Print to the screen the following header and beneath it a line of data that corresponds to…Suppose that classStanding is a char variable, gpa and dues are double variables. Write a switch expression that assigns the dues as following: If classStanding is 'f', the dues are $150.00; if classStanding is 's', (if gpa is at least 3.75, the dues are $75.00; otherwise dues are 120.00); if classStanding is 'j', (if gpa is at least 3.75, the dues are $50.00; otherwise dues are $100.00); if classStanding is 'n', (if gpa is at least 3.75, the dues are $25.00; otherwise dues are $75.00). (Note that the code 'f' stands for first year students, the code 's' stands for second year students, the code 'j' stands for juniors, and the code 'n' stands for seniors.)Rewrite the following expressions using the conditional operator. (Assume that all variables are declared properly.)a. if (x == y)z = x + y;elsez = (x + y) / 2;b. if (hours >= 40.0)wages = 40 * 7.50 + 1.5 * 7.5 * (hours - 40);elsewages = hours * 7.50;c. if (loanAmount >= 200000)closingCosts = 10000;elseclosingCosts = 8000;
