Can I assign the address of a integer variable to the float pointer?

Question

for example int a=4;
float *aPtr;
aPtr = &a;

Answer 1

Declaring a pointer to be a specific type tells the compiler when the pointer is dereferenced the value pointed to will be of that type.
if you run a code like that one, it would give an error: "cannot convert 'int* ' to 'float*' in inicialization", You can only assign addresses to pointers of the same type.

Answer 2

no
