Which code declares two variables, an 8-bit type named foo (initialized to hexadecimal FF) and an 8-bit pointer variable named bar that points to the variable foo?

1. int foo = 255; int bar = *foo;

2. char foo = 255; char * bar = foo;

3. char foo = 0xFF; char bar = foo&;

4. char foo = 255; char * bar = &foo;

5. char foo = 0xFF; char * bar = *foo;
