                                if(x==3){  strcpy(dd,dd3);   } 
                                if(x==4){  strcpy(dd,dd4);   }

                                if(x==6){  strcpy(dd,dd6);   }
                                if(x==7){  strcpy(dd,dd7);   } //printf("%s",dd);
                                if(x>7 || x<1)
                                {
                                       cout<<"\nPlease Enter Valid Option\n";
                                       goto Day ;
                                }
