Nested if-else statement

The word nested itself signifies one within another. Nested if-else statement also signifies the same, an entire if-else structure can be written the body of the if statement or the else statement or within both individually.

Syntax of nested if-else statement is as follows:

if(condition 1)
{
  if(condition 2)
    {
      statement 1;
      statement 2;
      --------------
      statement n;
    }
  else
    {
      statement 1;
      statement 2;
      --------------
      statement n;
    }
}
else
{
  if(condition 3)
    {
      statement 1;
      statement 2;
      --------------
      statement n;
    }
  else
    {
      statement 1;
      statement 2;
      --------------
      statement n;
    }
}
In the above syntax two if-else structures are used individually within if and else statements respectively.
