C MEMORY AND POINTER HELP

Can someone explain to me what things like

int *R[2] = {C, C + 2, C + 4};

or even

int *C = (memory address)

would mean in terms of the stars and pointers and the values? I know pointers are referring to memory locations, but im still trying to wrap my head around when they are values, when they are addresses, when addresses change vs. when the values change, etc.
