1.Implement a C++ program which reads any integer from a user until he or she enters ‘end’.This program must show all of the numbers which are read from a keyboard after ‘end’ is read.
2.Make a C++ program which concatenates two strings.Those strings are read from a user.This program should read which string goes first,as well.The concatenation process should be done not in the main function,but in another function you declare.You must not use strcat( ).
