Abstract:
Pushdown Automata (PDA) is one of the hierarchies of automata theory models appropriate for the design of compiler. This system implemented to detect the compile errors of the HTML program when basic beginners who write the HTML program in Notepad run this program in web browser such as Microsoft Internet Explorer, Netscape, Mozilla Firefox and so on. Now, basic beginners don’t know their errors after compiling HTML program. This thesis detects the compile errors by using the Pushdown Automata (PDA). The Pushdown Automata (PDA) uses the stack which can pop and push off the information. The advent of such system will provide the beginners with a guideline through which the beginners can see their errors of the HTML program. This system intends the basic beginners for teaching aids.
