Thread: Help with structures

Okay I'm going to make a C program (definitely not a homework this time) to keep track of timber (using structures) and I need your assistance.

Each unit of timber has got an identification code consisting of:
Zone - a character representing the zone of the tree:

Code:

char zone;

ID - a 10-character identification number

Code:

int ID[10];

Then I will define a structure called TimberIDType that contain the above information.

I would like to store the ff. information for each of the timber unit:

TimberID - of TimberIDType above
Kind - a 30-character description of the timber

Code:

char Kind[30];

Diameter, Weight and Height - float numbers that tell about the timber's dimensions

Code:

float Diameter, Weight, Height;

My program should be able to store up to 100 TimberRec records in an array called TimberArray.

My program should perform the ff. operations:

1. Add a new record into TimberArray
2. Display all records
3. Display a particular record given the Kind
4. Display records given the Weight
5. Display records given the TimberID

ff stands for "following" in this thread.

Okay, any further assistance so that I can put the segments into a fully-functional program? Please, I want it done by Monday (I'm not kidding).

I did a search and someone posted a very similar question on Daniweb last April. It most definitely is HW.

We'll talk about this later.

ID should be an array of char, not an int array, as Cactus_Hugger mentioned:
char id[10]; and all the dimension data should also go inside your struct:

char Kind[30];
float Diameter, Weight, Height;

Because every piece of timber will have that same type of info.

I don't see how it could have hurt anyone, so let's consider it a little white lie, and being the gentlemen (and ladies) that we are, understand that everyone uses such lies, from time to time, for purely good social reasons.

And simply pretend we didn't hear (or read) it. What lie?

As of this point in time I have defined the necessary structures and variables.

Here's what will the main menu will look like:

Code:

{...
//main menu
int choice1;

printf("\nWhat would you like to do?");
printf("\n[1] Add new timber record");
printf("\n[2] Display all records");
printf("\n[3] Display particular record(s) by kind");
printf("\n[4] Display particular record(s) by Weight");
printf("\n[5] Display particular record(s) by TimberID");
printf("\nInput choice: ");
scanf("%d",&choice1);
...}
