Answer
It is used when more than one condition are to be evaluated and only one of them is true.
The syntax of if-else-if construct is as follows:
if(condition 1)
Statement 1 //executed if condition 1 is true
else if(condition 2)
Statement 2 //executed if condition 2 is true
else
Statement 3 //executed if both conditions 1 and 2 are false
When 'condition 1' is 'True' then it will execute statement 1. In case 'condition 1' is false, the control will move to 'else if' part and will check 'condition 2'. If it is true, the control will execute 'Statement 2' otherwise it will execute 'Statement 3'.
