A C# program is being written to validate flight codes. Figure 1 shows the code for flight code length check and input.
Figure 1
1 int retryCount = 0;
2 Console.Write("Enter your flight code: ");
3 string flightCode = Console.ReadLine();
4 while (flightCode.Length > 8) {
5 string errorMessage = " exceeds maximum length";
6 Console.Write(errorMessage);
7 flightCode = Console.ReadLine();
8 }
9 Console.Write("Flight code verified.");
Rewrite line 5 in Figure 1 to concatenate the flight code with the string " exceeds maximum length", and store the result in the variable errorMessage.
Your answer must be written in C#.
