Without using strcat() function, write a C++ program that concatenates together 'n' number of strings input by the user following the specifications given below: a. The program asks the user how many strings the user wants to concatenate, and then gets 'n' number of strings from the user as input (one after another). b. The program must store the given input strings into a two-dimensional array where rows represent 'n' and column has a maximum size of 20. The program then concatenates all these strings into a one-dimensional array of maximum size as n 20) and displays the string on the screen
