In programming, what distinguishes a 'selection structure' from other control structures?
In programming, what distinguishes a 'selection structure' from other control structures?
- It chooses different execution paths based on conditions. (correct)
- It performs actions only once.
- It repeats a block of code until a condition is met.
- It executes actions in a specific order.

Nesting Structures
Nesting Structures
Placing one control structure (like a loop or if statement) inside another.
Null Case
Null Case
A situation in which no action is taken. Often used as the default case in a switch statement or when no conditions in an if statement are met.
Selection Structure
Selection Structure
A control structure that chooses different paths of execution based on conditions (like if statements or switch cases).

Study Notes
- Nesting structures involve placing one control structure, such as a loop or an if statement, inside another.
- Null case represents a situation where no action is taken.
- Used as the default case in a switch statement or when specific conditions in an if statement are unmet.
- Selection structure refers to a control structure that chooses different paths of execution.
- Paths are chosen based on conditions, such as if statements or switch cases.
- Sequence structure is the simplest control structure where actions are performed one after another in order.
- Single-alternative if represents an if statement that provides only one path of execution if the condition is true.
- No action is taken if the condition is false.
- Stacking structures involve placing one control structure after another in sequence.
- Structure is defined as an organized way to control the flow of a program, including sequences, selections, and loops.
- While loop represents a loop that repeats a block of code as long as a specified condition is true.
