Else-If Ladder Statement:      Else-If ladder statement is a multi-way statement.    The general format of else-if ladder statement is:

           

              Syntax:           if(condition1)

                                    {

 Statements-1

                                    }

                                    else if(condition2)

                                    {

                                            Statements-2

                                    }

                                    .

                                    .

                                    .

                                    else if(conditionn)                 

                                    {

                                                Statements-n

                                    }

                                    else

                                    {

                                          Statements-s

                                    }

                                    Next statements

Ø  First condition1 is evaluated.  It produces either TRUE or FALSE.

Ø  If the condition1 outcome is TRUE, then Statements-1 are executed and then control reaches to Next statements.

Ø  If the condition1 outcome is FALSE, then control reaches to condition2 and is evaluated.  If condition2 outcome is TRUE, then Statements-2 are executed and then control reaches to Next statements.  If condition2 outcome is FALSE, then control reaches to condition3 and so on.

            clrscr();

            printf("\nEnter Three Numbers:");

            scanf("%d%d%d",&x,&y,&z);

            if(x>=y&&x>=z)

                        printf("\nMaximum Number:%d",x);

            else if(y>=z)

                        printf("\nMaximum Number:%d",y);

            else

                        printf("\nMaximum Number:%d",z);
