4.THE ELSE IF LADDER:

There is another way of putting 15 together when multipath decisions are involved. A multipath decision is a chain
of 'if's' in which the stmt associated with each else is an if. It takes the following general form.

if(cond1)
Stmt-1;

else if(cond2)
Stmt-2;

else if(cond3)
Stmt-3;

else if(condn)
Stmt-n;

else
Default stmt;

Stmt-x;

This construction is known as else if ladder.
