| + | The switch statement is a multi-select control structure. An expression is evaluated once and compared to 'constants'. In case of equality, the 'statements' that come after the 'constant' are processed. In switch 'statements' can only ordinary data types (ie, 'int', 'long', char, short, etc.) can be used. | ||
