else
It’s a key phrase, through the use of this key phrase we will create a different block for “if” half. Utilizing else is all the time elective i.e, it’s endorsed to make use of once we are having alternate block of situation.
In any program amongst if and else just one block might be executed. When if situation is fake then else half might be executed, if half is executed then robotically else half might be ignored.
