Question

C++

Write a menu based program for the pet rescue. There should be 2 menu options

-Add a pet

-View pets

-If the user chooses option 1, you will open a data file for writing without erasing the current contents, and write a new pet record to it. The file can be formatted any way that you choose but should include the pet's name, species, breed, and color. You my also include any additional information you think is appropriate.

-If the user chooses option 2, you will open your data file for reading and print the information all the pets to the screen.

-Once you have completed the actions of the chosen option, return to the main menu and ask if the user would like to quit or perform another task.
