// Problem 5: encryptStrings (5 points) // Use pointer ptr to traverse the 2D character array 'strings' and encrypt each string in 2 step as follows- // 1) Reverse the strings. Hint: Use 'reverseStringsO for this step // 2) Shift the characters forward by the integer value of 'key' // If the string is "hello' and key-2, reversing will get you "olleh' and adding key to it will result in "qnnfj. // Once the value of key' gets larger, you will extend past alphabetical characters and reach non-alphabetical characters. Thats ok. // NOTE: DO NOT encrypt the null terminator character. Use the null terminator to find the end string If you could not implement reverseStrings0, skip using it in this function.
