[SOLVED] Help With C

[fob500]

Hi i have just started to read 'beginig unix programming' .Here is a sample code given in the book

#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdlib.h>
#include<stdio.h>
int main()
{
char c;
int in, out;
in = open(“file.in”, O_RDONLY);
out = open(“file.out”, O_WRONLY|O_CREAT, S_IRUSR|S_IWUSR);
while(read(in,&c,1) == 1)
write(out,&c,1);
return 0;

}
---------------------------------------------------------------------------------------------------
when i try to compile it the following errors are being displayed..

gcc -o 1 1.c
1.c: In function ‘main’:
1.c:10: error: stray ‘\342’ in program
1.c:10: error: stray ‘\200’ in program

1.c:10: error: ‘file’ undeclared (first use in this function)

It does compile perfectly on mine ... I can't really help, though.

I've seen this before, its the quotes in your program...or what you think are quotes are not really quotes. In my editor this is a quote " in your program this is what your using for quote ”. they look the same but they are not, look at them side by side ”" see how they differ. What are you using you an editor to write your program?

I didn't notice.

I didn't get it could you be more specific.I have tried changing the quotes " with '..It still gives a warning.When I try to run it doesn't produce the file.out which it should to copy file.in.

[gerard4143]

It's not a single quote, double quote thing. Your editor is using the wrong ascii symbol(s) for double quotes, its using the hex values 0xe2 0x80 instead of 0x22...What editor are you using?...G4143

[JeffGoldblum]

Yeah, with the quotation marks you have, I get the exact same messages, but it compiles perfectly with the proper quotation marks.

I'm using the normal text editor that ships along with Fedora 10.Please tell me if i can give more specific info and how to find it regarding the text editor..Thanx .

[gerard4143]

Is that editor Kwrite or Gedit?...G4143

When i put proper quotation mark It compile with no errors but a couple of warnings
