//#define EOF 0
int main()
{
// open the text file "fred.txt" for writing

// close the stream, so all changes to the file are saved

// open the file "fred.txt" for reading
FILE *in = fopen("kerg3470.03o", "rt");
// read the first line from the file
char buffer[100];
fgets(buffer, 20, in);
//display what we've just read
printf("The rinex version of:\"hanu.c\": %s\n", buffer);
fgets( buffer, 23 , in);
printf("The type of:\"hanu.c\": %s\n", buffer);

fgets( buffer, 40 , in);

printf("The type of:\"kerg3470.03o\": %s\n", buffer);
while(in==EOF)
fgets( buffer, 50, in);
printf("The type of:\"kerg3470.03o\": %s\n", buffer);

You could see eg http://stackoverflow.com/questions/2...he-line-length : note the comments on the getline() fn.
Fundamentally you need a loop of eg fgets() or whatever input fn you use.
Google has millions of results on this eg also read http://stackoverflow.com/questions/4...ne-using-fgetc

thanks a ton ! now i have another problem.. could u pls help with as to how to skip reading lines in btw while using fscnf statements.. and print only selected data...
thanks in advance....

Mate, seriously just google it; there are more C tutorials on the web than you could throw a compiler at ;)
Incidentally, you might also ask the Mods (via the Report button) to move this to the Programming forum.

Please always use code tags https://www.linuxquestions.org/quest...do=bbcode#code to post your code and use proper English, not 'could u pls help '.

Thank you.
