1. INTRODUCCION

En el presente documento se presenta el desarrollo de un analizador sintctico que crear la tabla

de smbolos de un programa, dicho programa es sobre clculos de reas y volumenes el cual est

programado en el lenguaje JAVA.

El presente muestra cmo se generan los autmatas, correspondientes a los diagramas sintcticos

cada lnea de cdigo del programa de clculos estadsticos, as mismo se presenta la tabla de

smbolos generada en relacin a los autmatas, que despus ser utilizada para la creacin del ya

mencionado analizador sintctico.

2 OBJETIVOS

2.1OBJETIVO GENERAL

Desarrollar un analizador sintctico, basndose en los diagramas sintcticos de todas y cada

una de las instrucciones del programa de clculos estadsticos, para con dicho analizador poder

generar la tabla de smbolos correspondiente.

2.2OBJETIVOS ESPECFICOS

generar los autmatas correspondientes a los diagramas sintcticos elaborados.

Disear los mtodos a utilizar para cada uno de los programas.

Disear la estructura de la tabla de smbolos del analizador sintctico.

Programar los mtodos.

Realizar pruebas de operacin.

Solucionar posibles errores de sintaxis.

7 CONCLUSION

Al realizar este trabajo obtuvimos un amplio conocimiento como alumnos debido a que la

materia promueve la retroalimentacin, mtodos de bsqueda de informacin y la

obtencin de soluciones para las diferentes dificultades que se presenten.

Realizar este tipo de Software brinda y proporciona la capacidad de analizar ms a fondo

el cdigo que se construy, el desarrollo de este analizador sintctico as como del Software

de clculos estadsticos fue realizado con lenguaje JAVA, el cual nos ah servido para

desarrollar la tabla sintctica, para el desarrollo de dichos Software como tal se

programaron los componentes mediante la aplicacin de cdigo.
