Do it in C++.

Task - Implement a class named ShiftCipher with a property called shiftAmount. - Implement encode and decode functions for the ShiftCipher class as follows, - encode function should take a string or a char array, and return another string or char array by shifting the letters in the alphabeth by the shiftAmount. For example, given the string "abcd" the function should return "bcde". You can achieve this by converting chars to integers, using ASCII representations to shift (eg. a=97,b=98 ), and convert back to chars. - decode function should take a shift encoded string or char array and convert it back to its original form. This function is the reverse of the encode function. Note: Do not compress your files, submit only CPP files.
