Answer:
To tell what will happen when an if-statement is false
Explanation:
We use else statement if if-statement get false.
for example
if(a>20)
{
print "your age is greater than 20"
}
else
{
print "Your age is less than 20"
}
In the pseudo code, you see the use of else statement, that if age is greater than 20 then display message "you are age is greater than 20". if this statement get false, i.e. you are age is not greater than 20 then else statement will be executed and message will be displayed that your age is less than 20.
Why other option are not correct
To input a variable:
to get input, we use input statement of respective programming language not if-else statement.
To end an if statement
we don't use else statement to end if statement. when condition met then if statement will be ended
To handle string value
we use input validation statement to handle if statement.
