    Which one has priority ?

    Hello and i'm sorry i opened a new topic for a question that may be embarrassing.

    Which one has priority in the statement of the below code ? Pointer is typecasted first and then the adress the pointer points to is incremented and dereferenced?

    Code:
    temp = *(uint32_t *)(frame + 1);
    Code:
    main(){
         fun1();
    }
    void fun1()
    {
         uint8_t frame[256];
         fun2(frame);
    }
    void fun2(uint8_t *frame)
    {
         uint32_t temp;
         temp = *(uint32_t *)(frame + 1);
         printf("%d", temp); }

    (frame + 1)
    is cast to
    (uint32_t *)
    and then dereferenced
    *
    and the result assigned to
    temp
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
