为了计算学生的成绩，在以下计算表中给出了成绩分布规则。请编写一个C语言程序来计算学生的成绩。

90 <= grade <= 100: A

80 <= grade <90: B

70 <= grade <80: C

60 <= grade <70: D

grade <60: F

根据提供的引用内容，学生的成绩按照以下方案计算：

- 如果分数大于或等于90，则得到A。
- 如果分数大于或等于80，则得到B。
- 如果分数大于或等于70，则得到C。
- 如果分数大于或等于60，则得到D。
- 否则，得到F。

这是一个嵌套的if语句，其中每个if语句都检查分数是否满足特定条件，并根据条件给出相应的等级。如果分数不满足任何条件，则得到F。

A car rental company rents out a variety of cars and coaches and its rental rates are calculated on a daily basis. The relevant information of vehicle is shown in the following form. You need to develop a vehicle rental system according to the following requirements. (1) Design a simple console interactive interface to provide users with the related information about this vehicle rental system including vehicle models, specific information, daily rent and discount information so that the user can make further choices. (2) After understanding the relevant information, the user can input the relevant information of the vehicle which he or she wants to rent through the console program. (3) The program calculates the rent that the user needs to pay and informs the user through the console program. (4) You need to deal with the illegal information input by users through the console with some rules and prompt the corresponding error reason.For example, the user cannot input a negative value for the number of parking days.You need to consider as many misinput cases as possible. Please submit program code and the screenshot of the program output in the answer

I'm sorry, but as an AI language model, I am not able to submit program code or screenshots of program output. However, I can provide you with guidance on how to approach this problem.

To develop a vehicle rental system, you can use a programming language like Python and create a console-based interface using the built-in input and print functions. Here is a general outline of how you can implement the system:

1. Create a list of vehicle models with their specific information (e.g., brand, model, seating capacity, fuel type, etc.), daily rent, and discount information (e.g., 10% off for renting more than 7 days).

2. Display the list of vehicle models and their information to the user using the print function.

3. Prompt the user to input the model of the vehicle they want to rent, as well as the number of days they want to rent it for, using the input function.

4. Validate the input to ensure that the user has entered a valid model and a positive number of days. If the input is invalid, display an error message and prompt the user to input again.

5. Calculate the rent based on the daily rent and any applicable discounts, and display the total rent to the user using the print function.

6. End the program.

Here is some example code to get you started:

# Define the list of vehicle models and their information
vehicles = [
    {
        'model': 'Sedan',
        'info': 'Brand: Honda | Model: Civic | Seating Capacity: 5 | Fuel Type: Gasoline',
        'daily_rent': 50,
        'discount': 0.1
    },
    {
        'model': 'SUV',
        'info': 'Brand: Toyota | Model: RAV4 | Seating Capacity: 7 | Fuel Type: Gasoline',
        'daily_rent': 70,
        'discount': 0.15
    },
    {
        'model': 'Coach',
        'info': 'Brand: Mercedes | Model: Tourismo | Seating Capacity: 50 | Fuel Type: Diesel',
        'daily_rent': 300,
        'discount': 0.2
    }
]

# Display the list of vehicle models and their information
print('Available Vehicles:')
for vehicle in vehicles:
    print(vehicle['model'])
    print(vehicle['info'])
    print('Daily Rent:', vehicle['daily_rent'])
    print('Discount:', vehicle['discount'])
    print()

# Prompt the user to input the model and number of days
model = input('Enter the model of the vehicle you want to rent: ')
days = input('Enter the number of days you want to rent it for: ')

# Validate the input
valid_input = False
while not valid_input:
    try:
        days = int(days)
        if days <= 0:
            print('Error: Number of days must be positive')
        else:
            for vehicle in vehicles:
                if vehicle['model'] == model:
                    rent = vehicle['daily_rent'] * days * (1 - vehicle['discount'])
                    print('Total Rent:', rent)
                    valid_input = True
                    break
            else:
                print('Error: Invalid vehicle model')
                break
    except ValueError:
        print('Error: Number of days must be an integer')
        break

This is just a basic example, and you may need to customize it further to meet your specific requirements and handle more edge cases.
