Question

Test 8 string Test8(sbyte offset, string message) Add the following method to your TextCodec class: public string Decode(string message) The purpose of the Encode() method is take the message passed into the method and decode it back to a readable string using the offset field stored in the class. The decoding code works nearly exactly the same as the encoding code, except you will subtract the offset from each character in the StringBuilder, instead of adding it. For this Test, when you have finished adding the above requested information to your TextCodec class, you will then make an instance object of type TextCodec, calling its overloaded constructor passing the offset variable given to you in this Test, and then you will call the Decode() method passing the message variable given to you in this Test, and return the result of the Decode() method. For example: TextCodec codec = new TextCodec(offset); // call the Decode() method passing message and return the result

Answer 1

The Encode() method in the TextCodec class decodes a message using the offset field.

Step-by-step explanation:

The subject of this question is Computers and Technology and the grade-level is High School.

The purpose of the Encode() method is to decode a message back to a readable string using the offset field stored in the class. To decode the message, you subtract the offset from each character in the StringBuilder. For example, if the offset is 2 and the message is 'abcd', the decoded message would be 'yzab'.

To complete the Test, you need to add the Decode() method to the TextCodec class. You then create an instance of TextCodec, pass the offset variable to its constructor, and call the Decode() method, passing the message variable. The result of the Decode() method should be returned.
