(426) CSC415 - Recall One Way versus Two Way Selection

One Way Selection: Involves a single decision point that leads to one of two possible outcomes based on a condition.

Two Way Selection: Contains two decision points, allowing for more complex branching scenarios, where each condition can lead to different paths based on multiple criteria.

Example of One Way Selection: An if statement that executes a block of code if a condition is true, otherwise it does nothing.

Example of Two Way Selection: An if-else statement that executes one block of code if the condition is true and another block if the condition is false.

Example of Nested Selection: An if-else-if statement that evaluates multiple conditions in sequence, allowing for more than two outcomes based on a set of criteria.

Additional Example of Two Way Selection: A switch statement that allows for multiple potential outcomes based on the value of a variable, providing a clear and organized way to handle different cases.

Comparison of Selection Types: One way selection is simpler and used when only a single condition is to be checked, while two way selection is more versatile, accommodating different paths of execution based on the condition's truth value.
