A naturalist is off to explore the amazon jungle, and needs a computer program to record information about all the new species discovered. For each new species it is necessary to store the name (max 128 characters), size (a real number), and the type of animal. mammal, insect, bird, or fish).
Here what a sample run should look like (with the keyboard input shown in italics) ...
NewSpecies
Enter animal information ("exit" to exit)
What is the name : bloatfish
What is the size : 12.47
What is the type : fish
Enter animal information ("exit" to exit)
What is the name : stingybeasty
What is the size : 0.13
What is the type : insect
Enter animal information ("exit" to exit)
What is the name : toothfulsloth
What is the size : 33.33
What is the type : mammal
Enter animal information ("exit" to exit)
What is the name : exit
The following new species were found:
bloatfish has size 12.47 and is a fish
stingybeasty has size 0.13 and is a insect
toothfulsloth has size 33.33 and is a mammal
You must
Implement the program in C. (3.0%)
An array of structures must be used, so that each new species can be recorded in an element of the array.
The type of animal is represented as an enum type, indicating one of mammal, insect, bird, or fish.
It's not known in advance how many new species will be found, so the program must malloc for an initial array
of size 1, and use the doubling realloc technique (as discussed in class) to get more memory as required. You must
always check the return value from malloc, as done in the Malloc wrapper function (or just use Malloc :-).
2)
Since we talked about pointers, memory allocation and linked lists in class, I'd like you to write a program that allows the user to:
Enter the names of persons.
For each person entered, enter the name of his/her best buddy.
Print out the "best buddys"
Here what a sample run should look like (with the user input shown in italics) ...
Enter nation name : Tom
Enter nation name : Betty
Enter nation name : Martin
Enter nation name : Michael
Enter nation name : Amanda
Enter nation name : Catharine
Enter nation name :
Enter best ally name for Catharine : Amanda
Enter best ally name for Amanda : Michael
Enter best ally name for Michael : Martin
Enter best ally name for Martin : Betty
Enter best ally name for Betty : Amanda
Enter best ally name for Tom : Catharine
The best ally of Catharine is Amanda
The best ally of Amanda is Michael
The best ally of Michael is Martin
The best ally of Martin is Betty
The best ally of Betty is Amanda
The best ally of Tom is Catharine
You must
Implement the program in C. (3.0%)
Each person's name entered must be stored in a node of a linked list.
Each node of the linked list must contain (only) the persons name, a pointer to the node for its best buddy, and a pointer to the next node in the list.
Before the program completes it must explicitly free the malloced memory.
