3 Array of strings In this assignment, you will implement a class called ECArrayofStrings. This class stores multiple strings and support multiple operations related to the strings. The header file of ECArrayofStrings is provided in the starter code. Here are some explanations. 1. We use STL vector to implement an array of strings. 2. Constructor doesn't take any input. 3. AddString: add a new string into the array of strings. 4. GetNumofStrings: return the total number of strings in the array. For example, suppose you use AddString to add two strings "abc" and "defg". Then GetNumofStrings should return "2". 5. GetMaxLen: return the maximum length of the (longest) string in the array. In the above example, this should return " 4 ". 6. GetLongestCommonPrefix: return the longest common prefix of all the strings. This is exactly the same as programming assignment 1 is supposed to do. You just need to turn this into a member function. 7. Concatnate: return the concatenated string. In the above example, return "abcdefg". Note: you need to follow the order of adding of strings: the earlier added strings should be dealt with earlier; the same for all the member functions in the class. 8. Dump: output to the standard output all the strings in the array each in new line (again, in the order of their addition). 9. GetLongestCommonPrefixofTwo: this is a private function (meaning that it is meant to be implementation only that is to be used in this class). You must use this in the GetLongestCommonPrefix implementation
