Chapter 5, Problem 9PS
Explanation of Solution
Given: Syntactical rules.
To find: The statement which is not a syntactical rule for the ‘if-else’ statement.
Solution:
The syntactical rules for the ‘if...else’ statements are:
The expression must be enclosed in parenthesis.
For an ‘if...else’ statement, no semicolon (;) is required; statements 1 and 2 have a semicolon as their types require.
The expression could have a side effect.
Both the true and the false statement can be any statement (even a different ‘if...
