Thank you. I don't know why this wasn't splitting string on my end.
It works with below string as well with no comma or ;



char tab[] = "house";


perfect. :)

Hi devs,

I am writing a code to parse strings with genetic information. Data are clunky with randomness.
For example,


I need name of each gene separately: GENE1, GENE2 and such. It is...

This is first time I am using getline.

If I code as the following I have to define line char array of a defined length. The column count is fixed in the input file, however, the characters in...

Thank you.

actually I didn't have a new line character in printing that is why poor ptinting.



void remove_trailingspaces(char *newlines)
{
size_t length = strlen(newlines);

Thank you for your reply.
I do not have any reason to parse first line (header). The posted data may not have tabs, but the file has. Attached is a small file with first few columns.

My goals are...

Hi there,

Please bear with me. I have a file with multiple columns. I would like split and perform some operations.
When I read file and split using strtok on tab separate it works fine, but I...

No problems.

I will try with #5.
If you get chance can you please review my code I put in my last post?

Thank you laser!

Any code you tried that you could share?

What are these series/numbers based on in each row?

hi laserlight,
the code (trim_whitespace(char *text) with *text = '\0'; in the end ) you shared doesn't work on my end.

Doesn't work mean I don't get the gene name, but complete line.
It could...

Thank you.

I guessed it could be an issue with local and global variable.
Now, I provide another array, copy into it and it works.





#include <stdio.h>

I read in file with four columns skipping line one. File is tab/space delimited, my goal is to get the last column.

I use function where parameter is char array. The function is OK as long it is...

Thank you. I got it.

I would like to store the returned in the result array, so I make changes as below after //
It gets annoyed with an error:





if I make above change I get error as

Thank you laser~!

I have never used strncat. I think the third parameter is for the number of characters to append. That makes me ask
in dest_maxlen - left_len - 1

is -1 at the end for the null character?
...

Thank you laserlight.

I have folowing questions:
1) I cannot understand why dest[0] = '\0'; is needed in the first place.

2) is it OK to mix size_t with C code? As far as I remember C doesn't...

Hi there,

I am new to C from biology background.
I have two char arrays I would like to concatenate. The expected output is two different strings. For example inputs are john and abbey.

The...

Hi Matt,
Thanks for your reply.

Hi,
My goal is to remove extra spaces from line.

I've tried multiple ways, many variables. But I get error for seg fault.

My code:



unsigned int j=0;

Hi laser,
Thanks much for your reply, and explaining in detail.
I'm still trying to absorb what you've said.

I've fixed my code or malloc.

Thank you again.

I can have 2D array as:

1)


char *p[10];

Or,

2)

gcc -v
gcc version 4.9.2 (GCC)

Compiling code:


gcc -g -Wall -Wextra *.c -o program_parse -pedantic -std=gnu99


I've a function which takes in a character array, parses it by tab. And...

Hi,
Thank you for pointing out to the error. Finally it got fixed. Compiler was annoyed with:


p=strtok(line,'\t');


in stead of:

if I include string.h anywhere else and compile, I get warnings as:
