Write a function in C++ to search and display details, whose destination is “Cochin” from binary file “Bus.Dat”. Assuming the binary file is containing the objects of the following class:class BUS{ int Bno; // Bus Numberchar From[20]; // Bus Starting Pointchar To[20]; // Bus Destinationpublic:char * StartFrom ( ); { return From; }char * EndTo( ); { return To; }void input() { cin>>Bno>>; gets(From); get(To); }void show( ) { cout<<Bno<< “:”<<From << “:” <<To<<endl; }}; |

Answer» void Read_File( ) { BUS B; ifstream Fin; Fin.open(“Bus.Dat”, ios::binary); while(Fin.read((char *) &B, sizeof(B))) { if(strcmp(B.EndTo(), “Cochin”)==0) { B.show( ) ; } } Fin.close( ); } |
