Her legacy can be felt every time you open a new window and point and click on your PC.

Adele refused to give Steve Jobs and his engineers a Smalltalk demonstration in 1979, suspecting that Apple would appropriate the technology. Xerox managers overruled her decision and the rest is history!

This programming language was used to create one of the first modern graphics user interfaces (GUIs) featuring windows, icons, menus, and pointers (WIMP), something most of us now take for granted.

Steve Jobs demanded to see a demonstration of Smalltalk-80 which she reluctantly gave him. Jobs and his team at Apple then incorporated Smalltalk-80 into the programming configuration of the Macintosh computer

Adele also created some of the design patterns that would go on to be the most commonly used in software design.

If the user enters the exit command, your shell should terminate (returning to the regular shell).

If the user entered an empty line, report an error and fetch a new line of input.

If your shell encounters EOF while reading a line of input, it should exit gracefully without reporting an error.

If your shell encounters an error while reading a line of input it should report the error and exit.

by using path expansion to locate the executable file (i.e. searching each directory in the PATH environment variable).

The user should be able to specify the command to execute by giving a path to the executable file (e.g. /bin/ls)

(functions that do not accept the size of your buffer are not able to prevent overflows whereas functions that do accept a size generally do; be sure to check the manpage of any function you use carefully).
