CISC 1110 Lab 24

For this lab, use the vet_record class you wrote in Lab 23. As a reminder, vet_record had three parts: an object of class animal_info, an object of class owner_info, and a balance_due field.

After creating the class definition, you wrote a declaration for an array of objects of class vet_record. You called it pet and it could hold info on 100 pets.

Now write two functions, one to read values into the pet array of objects, and one to print the pet array.

Start with the print_pets function, because it is a little bit easier to write. The function will receive two parameters, the array of objects of class vet_record, and n, the number of objects in the array. Neither parameter is changed in the function. The function will print the members of each object with messages in front of each, like this:

pet: Rover age: 5 type of animal: dog weight: 10.6

owner: Joe Smith phone: 718-555-5555

balance due: 5.60

Now write the read_pets function. The function will receive two parameters, the array of objects of class vet_record, and n, the number of objects in the array. BOTH parameters are changed in the function. The function will read in n and then read n sets of data values into the pets array. The function will read from a file called lab24.dat which is available on your class page, in the Labs section; download it and save it: http://www.sci.brooklyn.cuny.edu/~jones/cisc1110/Labs/lab24.txt

In the main program, call read_pets and then call print_pets.

Now, write code in the main program to use the collection of data you've just read in:

• Compare the weight of first pet (the one in pet[0]) with the weight of the last pet). Print the pet name and the owner last name for the pet which weighs the most.

• Print the names of all the dogs.

• Print the name, phone number, and balance due of any owner with a balance due over $25.
