Pointer to pointer member Struct

Question

Its a part of code that i working on. When i try to assign Diagcb.end to ptr2 it returned an error.

I tried to write it as:

ptr2 = &Diagcb.end;
ptr2 = &diagcb->end;

but the same error is returned.

typedef struct reportType {
    int a;
    int b;
    int c;
    int* ptr;
} reportType;

typedef struct cb {
    reportType* start;
    reportType* end;
    reportType arr[10];
}cb;
int fun (reportType* report);
main()
{
    cb Diagcb;
    reportType report;
    report.a = 0;
    report.b = 1;
    report.c = 2;
    report.ptr = NULL;
    reportType* ptr2;
    ptr2 = cb.end;
}

Answer 1

You should write it as ptr2 = Diagcb.end . Because Diagcd.end is already a pointer, you don't need to use & to get the address.
