A selection control structure is a programming construct that allows a program to make decisions based on certain conditions. It is used to control the flow of a program by selecting one of two or more paths based on the value of a specified condition.
Characteristics of a selection control structure include:
1. Condition: The selection control structure evaluates a condition or expression to determine which path to take.
2. Paths: The structure has two or more paths, each representing a different set of instructions to be executed based on the condition.
3. Decision-making: The structure allows the program to make decisions and choose the appropriate path based on the condition.
4. Execution: Only one path is executed based on the evaluation of the condition.
5. Control flow: The structure controls the flow of the program by determining which set of instructions to execute next.
6. Types: There are different types of selection control structures, such as if-else statements, switch statements, and nested if statements.
Overall, a selection control structure is essential for creating dynamic and flexible programs that can respond to different conditions and make decisions accordingly.
