1. switch-case syntax structure

switch（表达式/变量）
{
    case 值1：
        语句块1；
        break；           //break 表示跳出switch语句
    case 值2：
        语句块2；
        break；
    default：
        语句块3；
        break；
}

 2. switch-case and if-elseif similarities and differences:

The same point: the branch structure can be achieved

difference:

(1) if-elseif: range may process (bool value)

(2) switch: generally only for equivalence comparison
