Write out the Syntax of Nested if Statements?

The universal form is

                        If(expression 1)

                        {

                                    if (expression 2)

                                    {

                                                Statements 1;

                                    }

                                    else

                                    {

                                                Statements 2;

                                    }

                        }

                        else

                        {

                                    Statements 3;

                        }

In this, If the first expression is true then the following if statement gets executed and If the expression 2 is true then statements 1 gets executed otherwise statements 2 will be executed and comes out of the block and If the expression 2 is false, it comes to the final else statement and Statements 3 gets executed.
