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 'reversestrings()' 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 skip using it in this function. you will receive partial credit.
