Question $4$ The post office needs a program that reads in postal address data and then displays the data in a neat format. $$ Declare four string variables name, addr$1,$ addr$2$ and postalCode. $$ First, the main function of the program must input the data by means of a function called inputData. $$ Second, the main function calls the function displayData to display the name and address as follows: Mr R$.$S$.$ Bopape P$.$O$.$ Box $50741$ Sandton $2146$ Submit the program and the output.
