What is the difference between float pointer and int pointer address?

Question

I tried to run this code,

int *p;
float q;
q = 6.6;
p = &q;

Though it will be a warning, but i think &q and p

Answer 1

In addition to what is said by teppic,

Consider,

int a = 5;
int *p = &a;

In this case we indicate to the compiler that p is going to point to an integer. So it is known that when we do something like *p , at runtime, the no. of bytes equal to size of an int would be read.

If you assign address of a datatype occupying x number of bytes to a pointer of which is declared to hold the address of datatypes of fewer bytes than x, you read the wrong number of bytes when using the indirection operator.
