    struct,pointer and file

    hi,

    struct bike
    {
    char manuf[25];
    int id;
    bool rcode;
    char customer[25];
    int size;
    float rentcoast;
    bike *manufP;
    bike *idP;
    };
    int main( )
    {
    bike *temp;
    int code;
    char ch[20];
    ifstream filestr;
    filestr.open("lib/lab1.dat");
    ......
    ......
    }

    I want to write a function that will allocate storage for a new bike struct (a new node), read the data for the bike data members from a file named lib/lab1.dat, and return a pointer to the new node.
    how can I write this function?

    thanks.

    You can allocate memory with the 'new' keyword and the read the file with filestr.get()/filestr.getline() etc.
