Question

d. For each of the following strings, state whether it can be derived from the rules of the grammar of Figure 7.5. If it can, draw the corresponding syntax tree:

a + ( a )

a * ( + a )

FIGURE 7.5
A grammar for
expressions.
Nonterminal E
represents the
expression. T
represents a term
and Fa factor in the
expression.
N = {E,T,F}
T = { +, *, (, ) , a}
P = the productions
1. E → E + T
2. E → T
3. T T * F
4. T-F
5. F→ (E)
6. F→ a
S = E
