The structure switch-case chooses which part of the programming code to execute based on the calculated value of a certain expression.
switch (expression)
{
case 1:
statements;
break;
case 2:
statements;
break;
default:
statements;
break;
}

The switch statement is a clear way to implement selection among many options (namely, a choice among a few alternative ways for executing the code). It requires a selector, which is calculated to a certain value. The selector type could be an integer, char, string or enum. If we want to use for example an array or a float as a selector, it will not work. For noninteger data types, we should use a series of if statements.
