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 the following program for getting the line by line from a file.

#include 
int main ( void )
{
  char filename[] = "file.txt";
  FILE *file = fopen ( filename, "r" );

  if (file != NULL) {
    char line [1000];
    while(fgets(line,sizeof line,file)!= NULL) /* read a line from a file */ {
      fprintf(stdout,"%s",line); //print the file contents on stdout.
    }

    fclose(file);
  }
  else {
    perror(filename); //print the error message on stderr.
  }

  return 0;
}
