Switch

In computer science, a "switch" is a control structure used in programming that allows the execution of different blocks of code based on the value of a variable, typically an integer or a string. It enables multi-way branching by evaluating a variable against a set of possible constant values (cases) and executing the block of code associated with the matching case. If no case matches, an optional default block can be executed.Switch statements provide a clearer and more organized way to handle multiple potential values of a variable compared to a series of if-else statements. It enhances readability and can improve performance in certain scenarios where many conditions need to be checked.The structure of a switch statement typically includes the switch keyword, the variable to be evaluated, and multiple case labels followed by their respective code blocks. The switch may also handle "fall-through" behavior, where execution continues into the next case unless explicitly broken out.Overall, the switch statement is a fundamental feature in many programming languages, including C, C++, Java, and JavaScript, making it a common tool for developers when implementing conditional logic.
