I need some help with some programming.
I need to write a file that can search in a text file and read the whole line into a struct.
the struct =
and my file looks like this
lets say I need to find the BC109 in the file, then I need to get a struct of
Can someone give me the right answer on how to do this, I've been searching for days now.
You'll never find the "right answer", since other people probably don't have the same problem as you word-for-word, letter-for-letter, keystroke-for-keystroke.
Try breaking it down into steps instead. You'll get more done, and in doing so, probably figure out where to go next.
1) read it line by line. fgets() does that.
2) Check for BC109 at the beginning of the line. strncmp can do that.
2) break it into tokens. Lots and lots of ways to do that.
3) Put it into the structure. One sscanf would do it in a quick-and-dirty fashion. A safer way would be splitting into tokens and copying or scanning individually.
i founf out that i was not working with a space but a tab XD
My code works fine for tabs. That's why I used isspace(x) and not (x==' '), so it'd cover tabs or spaces. I don't know what you were running, but it wasn't my code.
That code works too, but has a very high probability of crashing whenever any of those fields are larger than your structure can hold.
I created python code that produce output in the form of:
moses-red-sea=1.00.03
genesis-snake=2.03
deliverance=5.0.010
I need to take this output and create a "C" header file and have it look like this:
struct {
char *name;
char *fixed_version;
} filename_versions... (7 Replies)
Hi,
I have received an application that stores some properties in a file. The existing struct looks like this:
struct TData
{
UINT uSizeIncludingStrings;
// copy of Telnet data struct
UINT uSize;
// basic properties:
TCHAR szHost; //defined in Sshconfig
UINT iPortNr;

Hi guys.
I have a header file including a structure like this:
typedef struct
{
int index = -1;
stack_node *head;
} stack;
But when compiling with cc it shows error at the assignment line (int index = -1):
error: expected ‘:', ‘,', ‘;', ‘}' or ‘__attribute__' before ‘=' token... (1 Reply)
Dear all,
I'm trying to manipulate a data file and putting a certain lines into one paragraph.
What am I actually want to do is that search some lines in a data file. These lines begin with "1\1\GINC-" and end with "\\@" or the following two empty lines as shown in blue.

Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
