First, how do you createOptionalobjects? There are several ways: Here is an emptyOptional: Optional<Soundcard> sc = Optional.empty(); And here is anOptionalwith a non-null value: Copy Copied to Clipboard Error: Could not Copy SoundCard soundcard = new Soundcard(); ...
to if(chk_block(&rec_buf_start, &chksum2 )) I get just 1 compile error: "potiner to different objects" Look at the prototype of chk_block and the declaration of rec_buf_start: bit chk_block(byte xdata *start_addr, word xdata *chksum ); ...
A pointer to function can be initialized with an address of a function. Because of thefunction-to-pointerconversion, the address-of operator is optional: voidf(int);void(*pf1)(int)=&f;void(*pf2)(int)=f;// same as &f Unlike functions, pointers to functions are objects and thus can ...
Pointer:A pointer variable may be reassigned to refer to different objects. Reference:A reference variable cannot be reassigned. It always refers to the object with which it was initialized. Usage Pointer:Pointer variables should be used when the possibility of referring to nothing exists or when ...
