After a program is successfully linked, it is in executable form.
To execute a program, enter the executable file name (either a.out
or the file name you used following the -o option). For example, to execute an object file named my_executable, enter:
The operating system searches for a file named my_executable according to
its usual search rules, calls the loader utility, and then executes the program.
Redirecting stdin and stdout |
 |
By default, standard input (stdin) and output (stdout) for the program are
assigned to the keyboard and display, respectively. You can direct standard
input and output by using the shell's redirection notation. For example, to
redirect standard input when you invoke my_executable, enter:
my_executable < input_data
|
The < character reassigns standard input to the file input_data. You
can redirect standard output in a similar fashion. For example,
This command uses the character > to redirect standard output for
my_executable to the file named results.
