The code then makes the second one c2 or s2 and copy of the first (-st and c2 - c1.) Then it changes a value in the data variable of the second (c2.data-1; and s2 data-1.). And lastly arines our dena fhom et a s Depending on the meaning of the assignment statement the value printed will be either 1 or a OUTPUT
