C Struct Worksheet

1. Write a struct called dog which has members for the name, owner, weight, and breed of a dog. Make all of your strings 30 chars (add an additional char for the null byte). Use a typedef to name the struct. Put your struct in the file dog.h.
2. Write the following functions to work with your dog struct. Put the prototypes in dog.h and the implementations in dog.c:
   • set a dog: parms are a pointer to a dog, name, owner, weight, and breed
   • print a dog: parms are a dog and a file pointer
3. Write a main function that creates two dogs. Use your functions to set your dogs and then print them to the screen. Use stdout as the FILE pointer when printing. Put your main in the file main.c and include dog.h.
4. Add the following functions to dog.h and dog.c
   • read a dog: parms are a pointer to a dog and a FILE pointer
   • isBreed: parms are a dog and a string (the breed), returns true if the dog is the same breed as the parm, false if not
   • ownedBy: parms are a dog and a string (the owner), returns true if the dog is owned by this person, false if not
5. Change your main to do the following:
   • Create an array of 20 dogs.
   • Open the file dog.dat for reading.
   • Create a function to read into the array; pass the FILE pointer and your array. Call your readDog function to read each dog, and return the number of dogs that are read into the array.
   • Print all the dogs.
   • Prompt for a breed and print all dogs of that breed.
   • Prompt for a name and print all dogs owned by that person.
