Explain switch statement, Computer Engineering

Assignment Help:

Switch

This is another form of the multi way decision. It is well structured, but can only be used in certain cases where;

  • Only one variable is tested, all branches must depend on the value of that variable.

The variable must be an integral type. (int, long, short or char).

  • Each possible value of the variable can control a single branch. A final, catch all, default branch may optionally be used to trap all unspecified cases.
