ashutosh4138:
nitish . can you show me dry working. plz
please read three topic...
pre increment and pre decrement operator... how it works...
post increment and post decrement....
fall through in switch means when there is no break statement ... in switch...
if you know all this i would explain...
so ... first case execute is 1 due to post increment... so there is no any case match therefore default execute and here is also post increment of i... so
first output :2 and return the new value of i=3
now second time loop run i=3 : pass through switch remember here is post increment so go for check case 3: here is incremented
