formatting fscanf

[tooswole23]

I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:

FILE *d;

d=fopen("t.dat" ,"rb");

where a, n are all strings.

fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,.. (etc)..,&n);

A sample of the Input file looks like this:
USB270.15385-29.63146 270.153847 -29.631455 2.966699e+03 -9.99 1.300391e+03 -9.99 -9.99 A-A-- 6.787463e+01 -9.99 1.555773e+02 -9.99 -9.99 10100 | ----- ------ ------ ------ | 0.373 13.554 12.928 12.670 AAA | ----- -------- - -------- - -------- - -------- - | --- ---------- - ---------- - --------- - --------- - --------- - ---------- -

fscanf doesn't know about column 1. Your parameter string tells it what to do. %s%s%s%s says to read the next four strings. If you call fscanf again with a %s it will read the fifth string. All whitespace, and that includes \n are ignored.

With all disc files, it is required you know the file layout.

In that case, how would I format it to take in the data for the first consecutive 5 strings and insert them into strings a to e?

[weaknessforcats]

That would be:

fscanf(d,"%s %s %s %s %s",&a,&b,&c,&d,&e);

But this assumes you have just opened the file or did a seek() to the beginning. Otherwise, this code just read the next 5 strings.

Note that these strings must be contiguous and not consecutive. Contiguous means nothing between the strngs.

Again, please note, you have to know where the strings are. fscanf cannot fish them out for you. If there are other values between the strings, then you need to read them also to position yourself correctly in the file.

if(d==NULL)

scanf("%d", &StarNumber);
return;
}

for(int counter=0; counter<StarNumber; counter++)
{
printf("The file was read correctly... Now inputing data of star number %d \n", counter+1);

fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s", &star[counter].RA, &star[counter].Dec, &star[counter].irac1,  &star[counter].irac2,  &star[counter].irac3,  &star[counter].irac4,  &star[counter].mips,  &star[counter].qual,  &star[counter].Erirac1, &star[counter].Erirac2,  &star[counter].Erirac3,  &star[counter].Erirac4,  &star[counter].Ermips);
}	

int a=0;
printf("Show data of which star?");
scanf("%d",&a);

printf("Name:%s \n RA: %s \n Dec: %s\n Irac1: %s\n Irac2: %s\n Irac3: %s\n Irac4: %s\n Mips: %s\n qual: %s\n ErIrac1: %s\n ErIrac2: %s\n ErIrac3: %s\n ErIrac4: %s\n ErMips %s\n", &star[a].name, &star[a].RA, &star[a].Dec, &star[a].irac1, &star[a].irac2, &star[a].irac3, &star[a].irac4, &star[a].mips, &star[a].qual, &star[a].Erirac1,&star[a].Erirac2, &star[a].Erirac3, &star[a].Erirac4, &star[a].Ermips);
	
}

I've been testing the code for the first star, and the way I have it set up it should just read the first 14 strings of the line with the fscanf, unless I'm mistaken.
It returns 14 consecutive strings, but starting on the 13th string as opposed to the the 1st string

formatting the fscanf get the sscanf and scanf

When you ask to print the first star, are you asking for 1 or 0? The first star is 0.

[tooswole23]

I'm asking for the 0th star.
