Arguments tab

This tab lets you specify the arguments your program uses and the directory where it runs.

The Arguments tab in the Launch Configurations dialog.

C/C++ Program Arguments
Enter the arguments that you want to pass on the command line. For example, if you want to send the equivalent of myProgram -v -L 7, type -v -L 7 in this field. You can put -v and -L 7 on separate lines because the IDE automatically strings the entire contents together.
Working directory on target
The option Use default working directory is set on by default. This means the executable runs in the /tmp directory on your target. If you turn off this option, you can click Browse… to locate a different directory.
