Using c++ create a library with following functions (prototypes are given along with a description):

- void increasing (double& A, double& B, double& C); //Arranges A, B, and C in increasing order.

- void decreasing (double& A, double& B, double& C); //Arranges A, B, and C in decreasing order.

- void mmm (double& A, double& B, double& C); //Replaces A with the minimum of A, B, and C; replaces B with the average of A, B, and C; replaces C with the maximum of A, B, and C.

Use the library in a program where the user is asked to enter three numbers. The program calls all three functions above and outputs the new values of A, B, and C for each case. Do not just output numbers. Display a message with each result.
