Can switch statement be nested?

It is possible to have a switch as part of the statement sequence of an outer switch. Even if the case constants of the inner and outer switch contain common values, no conflicts will arise. C++ specifies that at least 256 levels of nesting be allowed for switch statements.

Can we use nested switch in C?

It is possible to have a switch as a part of the statement sequence of an outer switch. Even if the case constants of the inner and outer switch contain common values, no conflicts will arise.

Is switch statement more efficient than if?

A switch statement is usually more efficient than a set of nested ifs. The compiler can do this because it knows that the case constants are all the same type and simply must be compared for equality with the switch expression, while in case of if expressions, the compiler has no such knowledge. …
