GUYS HELP ME I HAVE NO CLUE HOW TO DO THIS

Using the following grammar:

<expression> := <component> | <component> + <expression>
<component> := <factor> | <factor> + <component>
<factor> := <positive integer> | (<expression>)
write a program which analyses expressions conforming to the rules of this grammar and evaluates them, if the analysis has been successfully completed. It may be assumed that there is no overflow of float(C)/real(Pascal) numbers range.
