Ptr=&x is incorrect whereas ptr=&a is correct because a is int type and pointer also of same datatype but as we can see x is of float datatype but pointer is still a int datatype hence a is correct but not in case of x 👍🏼👍🏼

[@tonysofla]

C is supposed to be ab abstract layer for different cpu hardware. that is like why you can't use Carry for example. But what all cpu/mcu have is opcode for indirect addressing.
That is what C pointers let you access, so just think that all struct data are Tetris blocks that repeats at some offsets and intervals, the C-pointer is to point this part of memory as it has already been pre-allocated at compile. So, it's like a gray area of what C allows: direct memory access. And if you do want it, can be done with type casting a pointer: *(INT*)0x1000

Ptr can't contain address of x as it is float while ptr can store address of that variable only whose data type is int 17:15

[@bawaabdulsilas3681]

float = x, y; - is a valid declaration in C.
int a, *ptr; - Is also a valid declaration in C.
ptr = &x - Not valid, because x and ptr are not the same data type (i.e while x was declared using "float" data type, ptr was declared using "int" data type as such, ptr cannot point to x).
ptr = &a - This is valid because both were declared using the same data type which is int. So by implication ptr should be able to store the address of a.
So, at last ptr will contain the address of a, say... 2001.

Would that be a dangling pointer if we declare a variable after assignment of pointer to the address of that variable ??
It would take the value whichever is newly assigned

Thank you for your lectures on C programming language. At 11:19 int a = 10; int* p ; p = &a; these I assume correct. But at 14:18 int a = 10; * p = &a; I think it would be like *p = 10 as 'p' contains the address of 'a'.
