int i;
char j;
char *ip;
for (i = 0; i < 10; i++)

ip=&j;
for (j = 0; j<3; j++)
{
FILE *fp;
char filename[17] ;
if (i == 0)
{
strcpy(filename , "injection-0");
if (j==0) strcat(filename ,"_11.txt");
else if (j==1) strcat (filename,*ip);
else if (j==2) strcat (filename,"_12. txt");

I don't believe you have to dereference the pointer.

Hi,
I have the following code:
char request = "GET ";
strcat(request, path); //Path is the path section of a url ie. "/path/test.htm"
strcat(request, " HTTP/1.1");
cout<<request<<"\n"; //This outputs "GET /path/test.htm HTTP/1.1" happily
//Send packet (I know there's no error checking, this is just an example)

Hi,
Having not done any C programming for a while I am trying to get back into
it by converting an old java assignment into C.
The problem is I am getting a segmentation fault at runtime which I am
having trouble fixing(program below)
The idea of the program is to convert input(integers) into words eg:
# 101
returns
#one hundred one
I have found the problem is with the strcat of the strings & literals --

Hi,
Continuing my strcat segmentation fault posting-
I have a problem which occurs when appending two sting literals using
strcat.
I have tried to fix it by writing my own function that does the strcat
(mystract). Program below.
However this appears not to have fixed the problem and I don't know why it
shouldn't ?
Any further help as to what else I am doing wrong will be appreciated
regards

Here is the relevant code:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
