• Change the first example, so that it writes you name, instead of "Hello".
• Find a Pascal compiler named Free Pascal, install it and test the second example program.
• Change the second example, so that it writes you name.
• Find a C compiler for the operating system you are using (on Linux it is probably installed; on Windows or Mac OS X, you can try CodeLite) and test the third example program.
• Change the third example, so that it writes you name.
