InlineVariableInExpressionTree

Correction

Here is what's right.

The expression tree represents a syntactic decomposition of an expression (a parse tree, or abstract syntax tree, of the expression). How the value of a variable was computed is not visible in an expression tree showing a read access of that variable.

For example:

int v = 1 + 2;
int result = v + 4;

The expression v + 4 should consist of only three nodes: ”+”, “v”, and “4”. Students holding this misconception will inline the expression used to assign a value to v, and thus draw an expression tree involving 5 nodes: ”+”, ”+”, “1”, “2”, and “4”.
