The if-else statement is used to express decisions where else part is optional.
Syntax:
if(expression)
statement1
else
statement2
The expression is evaluated; if it is true (i.e. if the expression has a non-zero value), statement1 is executed. If is false and if there is an else part, statement2 is executed instead.
Since an if simply tests the numeric value of an expression, if(expression) can be used instead of if(expression!=0).
