Why are you making this so complicated?
There seems to be a lot of questions about linked lists on this board. This is how I approach them.
First, in order to simplify the explanation I am going to use a very simple structure.
It will...
All of the above is correct. As far as the offer goes it's the total amount still available divided by the number of cases remaining plus a little bit for incentive.
Ex 1:
Lets say there are...
Here's how I do it. I load a string with the entire command and pass it to the system call.
sprintf(sysstr,"program_name %d",variable);
system(sysstr);
You have another problem in getdata(). When you read the entire file to get a line count the file pointer stops at EOF and remains there. In order to load your structure array you must call either:
...
Have you ever though of using the shared memory functions that are part of IPC from Unix SVR4?
Take a look at this:

In addition to all the points made by Master5001, I can tell you one reason it won't work. You're not passing the var "count" into the functions as a pointer, so when you increment it in your...
These types of things are interesting. Look at this table:
(0 represents space or padding)
000010000
000232000
003454300
045676540
567898765
10 is the ascii value for a newline '\n'
When you hit enter a newline is appended to the buffer.
fgets then appends a null to terminate the string.
You are processing the newline as part of...
I don't know if this would help, but have you thought of using IPC
(inter process communication) messaging.
I use it for communication between a database engine and applications.
Here is a URL...
Your imput buffer (line) has no memory allocated for it. The best way is to declare line like:
char line[1024];
That will allow up to 1023 bytes of input.
The segmetation fault is caused...
Mats is right. I have found that the best use for signals is when you need a program to behave in a specific way without human intervention, such as forcing a timeout. The setup is somewhat...
On output only. Let's say x = 12;
printf("%d",x) produces 12;
printf("%04d",x) produces 0012;
The leading 0 will pad the output.
First, let me say that this information is going to stored in a simple array. If you were taklking
about a large amount of data a binary tree (tsearch) would offer much better performance at
the...
The problem is that you have two "main" functions. The main function is always the entry point and you can only have one. There are three solutions.
First change the second program to a function....
Your loop will work as well, and actually is more elegant.
Let's start from the beginning. The issue is that when presented with a string we want to convert lower case letters to uppercase letters without effecting any other charactor types.
This means:
...
It only converts it if it is NOT equal to zero
You should use "islower()". Remember, these charactor type functions return NON-ZERO for true. So you could do:
if(islower(c) != 0)
x = toupper(c);
Since a linked list is only defined by each nodes embedded pointer what you need to do is create a double linked list. Each node must contain a pointer to the previous node as well as the next one....
