How do I execute a.out?
Author
Im new to linux, and I compiled a simple program for it with gcc (a hello world of sorts), and it went to a.out -- but I can''t figure out how to run this...

In Linux, the current directory isn''t usually in the search path, so you need to specify where the executable is with the ./

God puts an apple tree in the middle of the Garden of Eden and says, do what you like guys, oh, but don''t eat the apple.

They''ll get you in the end. -- Douglas Adams

I guess that is doing it -- but why would the following program
#include <stdio.h>

#include <stdio.h>
int main()
{
printf("look -- Im using printf");
return 0;
}
do nothing?
thry this instead
printf("look -- Im using printf\n");
... you need to print before your buffer is filled up, so just use special char ''\n'' for that, it''s the new line char.
printf("look -- Im using printf\n");

Hopefully by now you also know that you can specify the name for your compiler output file using the -o (lowercase! uppercase is for optimization level) option:
gcc hello.c -o hello
