Write a short program in $C++$ with the following functions:

void input$($std::string &first, std::string &second$)$

requests two values of type string from the user, accepting the values from standard input

returns the accepted values by reference

void swap$\_$strings$($std: :string &first, std::string &second$)$

accepts two string reference arguments and swaps the referenced values. In other words, the string stored at the first parameter ends up stored

in the second parameter and the string stored at the second parameter ends up stored in the first parameter.

void output$($std: :string &first, std: :string &second$)$

that prints two strings to the screen with a space between them.

int main$()$

Uses the input, swap$\_$strings, and output functions to:

Accept two string values from the user.

Print the received strings in their original input order

Print the received strings in reverse of the original order.

Again, print the received strings in their original input order
