Reading one line at a time in C

Question

Which method can be used to read one line at a time from a file in C?

I am using the fgets function, but it\'s not working. It\'s reading the space

Answer 1

use either fgets if you know that your lines will fit into buffer or use fgetc for more control over reading

Answer 2

If you are coding for a platform that has the GNU C library available, you can use getline():

Source of Error:

Actually it was not my fault.. In this case . I was using strtok function and and accidently modified my original my original string. Hence while printing I was getting the error...

Thanks Everyone for Helping me.. :)

Answer 4

The fgets function will read a single line from a file or num characters where num is the second parameter passed to fgets. Are you passing a big enough number to read the line?

For Example

// Reads 500 characters or 1 line, whichever is shorter
char c[500];
fgets(c, 500, pFile);

Vs.

// Reads at most 1 character
char c;
fgets(&c,1,pFile);
