Hi friends,
I'm new to this community. i just want to read string from a file excluding punctuations like ',' ';' or newline character. Is there any way to read the string by specifying the terminate character.

There isn't a built in way of doing this. You would need to write a parser.
1. Read each line of the file into a buffer using fgets (assuming you know the maximum line length).
2. Walk through the string until you come to the next separator, and copy what you've read into a buffer.

Thanks 4 ur reply. Yeah, thats i know.Is it possible to use fscanf to read the string using format specifier like ^[a-z] or ^[A-Z]?? i've come across the net about this fscanf thats why i'm asking. Is there anyway to read the string using fscanf for my requirment??
fscanf(fptr, "%[^;]", str);
unsigned int eof = 0;
while(fscanf(fptr, "%[^;]", str) && !eof) {
printf("%s\n", str);
fgetc(fptr);
eof = feof(fptr);
}
unsigned int eof = 0; while(fscanf(fptr, "%[^;]", str) && !eof) { printf("%s\n", str); fgetc(fptr); eof = feof(fptr); }
Hi Martin,
How can i specify more than one character in %[^;]? I want to include the character like '{' and '\n'.
You just add them inside the square brackets after the ^.
[^;{\n]

[^;{\n]
Thanks martin, Could u please explain elaborate about this ^[...] , [^..] function using some more special character and program. I tried [^;}\n] but it terminated when it find '\n' but i mentioned '}' before '\n' and the '}' is present last of my file.So i don't understand.
The ^ means "none of these", so [^;}\n] should cause it to stop reading the string when it encounters a ;, } or \n.
