using System; class Program { static void Main() { int adultTickets, childTickets; Console.Write( "How many adult tickets are needed: " ); if (! int .TryParse(Console.ReadLine(), out adultTickets) || adultTickets < 0) { Console.WriteLine( "Invalid input. Please enter a valid positive integer for adult tickets." ); return ; } Console.Write( "\nHow many child tickets are needed: " ); if (! int .TryParse(Console.ReadLine(), out childTickets) || childTickets < 0) { Console.WriteLine( "Invalid input.

Write a program to calculate and display the potential difference between the ends of a wire. The program will prompt the user for the current flowing and the resistance of the wire. Potential difference is the product of the current and the resistance of the wire and may include a fractional part. (Again, use the "F" format-specifier for floating point values). using System; class Program { static void Main() { double current, resistance; Console.Write( "Enter the current: " ); if (! double .TryParse(Console.ReadLine(), out current)) { Console.WriteLine( "Invalid input. Please enter a valid number for current." ); return ; } Console.Write( "Enter the resistance: " ); if (! double .TryParse(Console.ReadLine(), out resistance)) {
