An alternative to nested ifs Similar to Matlab

The goto and break keywords The switch statement

Averting from using goto is strongly suggested Complicating your codes

Fall through you cannot fall through to the next ca

nt the following message * ** *** **** *****

Debugger

Example

Alarm system (3-15)
