Program 1:(C# please) Design (pseudocode) and implement (source code) a program (name it PhoneBill) that calculates the bill for a cellular telephone company. The company offers two types of service: regular service 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. Document your code and properly label the input prompts and the outputs as shown below.

Program 3: (C# please)Design (pseudocode) and implement (source code) a program (name it Circles) to determine if a circle is either completely inside, overlapping with, or completely outside another circler. The program asks the user to enter the center point (X1, Y1) and the radius (R1) for the first circle C1, and the center point (X2, Y2) and the radius (R2) for the second circle C2. The program then determines if the second circle C2 is either completely inside, or overlapping with, or completely outside the first circle C1. Hint: use the sum of R1 and R2 and the distance between the centers to solve the problem. Document your code, properly label the input prompts, and organize the outputs as shown in the following sample runs.

Program 4:(C# please) Design (pseudocode) and implement (source code) a program (name it IncomeTax) that reads from the user annual income, as integer value, and calculates the income tax based on the tax table below. Income Tax bracket Annual income <= $50,000 5% $50,000 < Annual income <= $200,000 10% $200,000 < Annual income <= $400,000 15% $400,000 < Annual income <= $900,000 25% $900,000 < Annual income 35% The program output should include the entered annual income followed by the applied tax bracket and the tax amount. Document your code and properly label the input prompts and the outputs as shown below. Note: Taxes are computed based on brackets. For example, if ones income falls in the 25% bracket, the first $50,000 is taxed at 5% rate, the next $150,000 is taxed at the 10% rate, the next $200,000 is taxed at 15% rate, and the remaining income is taxed at the 25% rate. See sample run 3 below.

Program 5: (C# please)The concept of a 5-digit palindrome number is a 5-digit number that reads the same from left to right and from right to left. For example, 12121, 45454, and 14741 are valid 5-digit palindrome numbers. Design (pseudocode) and implement (source code) a program (name it FiveDigitPalindrom) that reads a 5-digit number from the user (as integer value, not string) and then mathematically (using division and remainder operations) determines whether the entered number is a 5-digit palindrome or not. Assume valid inputs are from 11111 to 9999. The program rejects any input outside that range with the message Invalid 5-digit number. Try again. Document your code and properly label the input prompts and the outputs as shown below.
