Access to an array of structures using pointer notation

I am trying to learn C ++ myself and am trying to do this. I have a structure whose member is an array of other structures. I have a question about alternative notation.

The structures that I defined

struct employeeRecordT {
    string name;
    string title;
    string ssnum;
    double salary;
    int withholding;
};

struct payrollT {
    int num;
    employeeRecordT *array;
} payroll;

I allocate memory for payroll using the following construction

payroll.array = new employeeRecordT[payroll.num];

where payroll.num indicates the number of elements in the array. I can access the element name employeeRecordT using array notation, for example.

payroll.array[i].title

I wanted to know how to access this using pointer notation, I tried

payroll.(array+i)->name = "Vikas";

and I get the following error message from g ++

toy.cc30: 13: error: unqualified identifier expected before '(' token toy.cc30: 14: error: 'array' was not declared in this area
