Design ( in C#) and implement a program that calculates the bill for a cellular telephone company. The company offers two types of service: regular servicer and premium service. The rates vary depending on the type of service. The rates are computed as follows

Regular service: $15.00 fee covering first 50 minutes. Charges for over 50 minutes are computed at the rate of $0.50 per minute.

Premium service: $25.00 fee plus:

a. For daytime calls (between 6:00AM to 6:00PM), the first 50 minutes are free; charges for over 50 minutes are computed at the rate of $0.20 per minute.

b. For nighttime calls (between 6:00PM to 6:00AM), the first 100 minutes are free; charges for over 100 minutes are computed at the rate of 0.10 per minute.

The program prompts the user to enter an account number, a service code (of type char), and the number of minutes the service was used. A service code r (or R) means regular service; while code p (or P) means premium service.

If the service is premium (code p or P), the customer may be using the service during both the day and night. Therefore, the program must ask the user to input the number of minutes used during daytime and nighttime in separate prompts.

Example:

Account Number: 12345 Service type: Regular Total minutes: 50 Amount due: $15.00
