This might be annoying but i really don't understand the switch statement.

Question

Can someone answer the switch simply?😵Cuz I really don't understand the meaning and how its used.Also pls give some examples.☺

Answer 1

switch(var){//evaluate var
case 2: //in case var equals 2
.....//do something
break; //stop the switch statement
case3:
.....//do something else
break;//same as above
default:
....//do default action
}

if var is two the switch statement will execute the instructions in the "do sometimg" line
and exit due to the "break;" folloing the instructions
if var is 3 the switch statement will execute the instructions in the "do someting else" line
and exit due to the "break;" folloing the instructions
if var is 1 the switch statement will execute the instructions in the "do default action" line because case 1 and casr 2 are not met,
and exit due to the end of the switch statement.

if you dont use "break;" after the case, also the instructions of the next cases will be executed until next available "break;" or the end of the statement.

Now, if you want to really understand it, start typing and do your experiments with switch statements.
