1. (6 pts) Considering the following code part, assume that each integer occupies 4 bytes, list how much memory space (in bytes) is required for all available variables at point B, C, D, E,F and G. (the memory space required at point A is given). Note: Pay attention to the int a, b,c // Point A: 12 bytes nt d // point B: bytes int e,J I/ point C: bytes // point D: bytes // point E: bytes int x y // point F: bytes // point G:bytes
