switch case C++

The switch operator in C++ allows for the selection of one of many code blocks to execute based on the value of an expression. The syntax involves a switch statement followed by a series of case statements, each with a value to compare against the expression, and an optional default statement for when no case matches. The expression is evaluated once, and the corresponding code block is executed if a match is found. Break statements are used to exit the switch block after executing the matched case, and default is optional.
