Hi Friends,
I have written a code which suppose to read all the numbers from a hex
file,But to my surprise the code is skiping every alternate value.Don't
know why?
Can you please help me in solving this problem.
The code is as follows;
main ()
{
FILE *fdataptr;
int x;
int ctrl;
x=1;
// Open the file containing data
fdataptr = fopen("data.txt ", "r");
if(fdataptr==NU LL){
printf("\n Cannot open File data.txt");
exit(1);
}
do {
fscanf(fdataptr ,"%x", &ctrl);
printf ("\n\n data is 0x%x \n\n",ctrl);
if (fscanf(fdatapt r,"%x", &ctrl)==EOF)
break;
} while (x);
}
data.txt is having the values
11111111
22222222
33333333
44444444
55555555
66666666
77777777
88888888
99999999
Thanks & Regards,
RSK...

Because you read and ignore every second number?

do {
fscanf(fdataptr ,"%x", &ctrl);
printf ("\n\n data is 0x%x \n\n",ctrl);

Can you correct me to print all the data values

Please quote some context when you are replying.
I'm not going to correct your program for you. I've already told you
what you are doing wrong, and I think it's now down to you to correct it.

Look how many times you are calling fscanf. Hint : too many times in the
loop.
Aha!

should be

No, it shouldn't be that. If fscanf doesn't read ctrl, it doesn't set ctrl;
ctrl isn't somehow set to EOF.

No, it shouldn't.
The proper solution is to structure the loop more intelligently:
while(fscanf(fd ataptr,"%x", &ctrl) == 1)
{
printf ("\n\n data is 0x%x \n\n",ctrl);
}

This loop calls fscanf() twice. You're only printing the result from the
first call. The results from the second fscanf() are discarded.
Change your loop to only call fscanf() once.

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.
