Discuss the advantages of expression tree, Computer Engineering

Assignment Help:

Discuss its advantages over the other evaluation techniques.

The expression tree is determined by using a post-order traversal of the expression tree as given here:
1. If such node has no children, this must return the value of the node
2. Calculate the left hand child
3. Calculate the right hand child
4. Then calculate the operation indicated through the node and return this value
An expression tree is advantageous for:

  • Understanding the sequence of operation. Operations which must be completed sooner are further to the right in the tree.
  • Counting the no. of terms or factors in an expression. All terms or factor is a child node. For illustration the expression (a+b)/c+2*d contains two terms.
