Thread: Plz help me, got stock ..

You need to compile your program, using say

gcc main.c

The result of that is an executable program called a.out (if all is well), which you run with
./a.out data_file.txt

but the main file does not has any extension, mean its only "mean" not "mean.c"
when I change it's name to mean.c, I got some unreadable things inside this file.
can u help me again plz, thanks alot

File extensions are not used on Linux for determining whether something is executable, however, gcc itself uses the extension to tell it something about the input file. For example, a text file with a .c at the end means it is a C source code file. Renaming an executable file as .c, for example, is wrong.

Try the following command

gcc -o main main.c

That means to compile a text file called main.c and output an executable file called main. Then you should be able to do this if it worked:

./main

Code:

$ ls -l a.out
-rwxrwxr-x 1 user usergroup 8844 2013-02-10 14:06 a.out
$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped
$ file bar.c
bar.c: ASCII C program text

First you do "ls -l" on your main file. Is it marked as executable? (that's the first 'x' in the rwxrwxrwx permissions) If it isn't, then you can't execute it.
Then you use the "file" command to see what kind of file it is. If it lacks any mention of "executable" (like bar.c has, which is just C program text), then you can't execute it.
Now do "ls -l" on your data file. Is it owned by you? does it have 'r' permissions on it?

The next step is to post your results and save the interpretation for us.

You post facts, we analyse and inform.

Are you saying that you unzipped "c code.zip" and found an executable, and then tried to run it?

FWIW, you should create subdirectories before unzipping files. In your home directory, there are a large number of "dot-files" (do "ls -a" to see them). Trashing these by unzipping some errant zip file can effectively trash your account.

Try these

Code:

$ file main
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped
$ uname -m
x86_64

Unless the architecture is the same, you're unlikely to succeed.

Also, if main didn't come from the zip file, where did it come from?

Ordinarily, it should be the result of some compiling, like
gcc -o main prog.c

Show us how you came to have main in your directory.
