[C] using getchar() and putchar() to read in files

[sozener1]

Im working on some programme

and I've used getchar() putchar() to read sentences in a text file

I open the file usin stdin < filename.txt format

and here is my code

#include <stdio.h>
#include <string.h>


int main(int argc, char *argv[]) {

int i;
printf(" ");
while((i=getchar())!='l'){
putchar(i);
}



return 0;

}

and here is the first few sentences in the file

"Project Gutenberg's Alice's Adventures in Wonderland, by Lewis Carroll

This eBook is for the use of anyone anywhere at no cost and with"

the code works fine for most part and prints out every single characters correctly including the space EXCEPT for "P" from Project in the first sentence

it gets printed out in a very weird symbols

can anyone help me figure out what is wrong

You're not reading from a file. You're reading keyboard inputs and showing them on the screen. You even didn't open a file!
Take a look at here.

no I am not meant to open files in here

But you said you want to read sentences from a file!
Anyway, the code you posted, only reads keyboard inputs!

He is reading from stdin, and if you look at how he calls his program, he reads from the file.

Use 'od' or some similar program to look at the first few bytes in your input file.

Are you sure it is a simple ASCII file and not UTF-8 file with BOM (http://en.wikipedia.org/wiki/Byte_order_mark )?

Edit: that's actually the same hint Nugatory gave, he was just faster. I hate being interrupted when posting

Poster indicated in his opening post that he is using the operating system to perform redirection of file to stdin.

 

[thankz]

it would be something like cout >> txt.txt , (but that's prob not right lol) look for some tuts for like this http://www.cs.bu.edu/teaching/c/file-io/intro/
