| The statement ''fulladder fa[8];'' creates an array with 8 instances of full adder and the carry chain between adders is connected by bool array ''c''. The statement ''(i:8: ….)'' implements a loop with index ''i'' and its value runs from 0 to 7. | The statement ''fulladder fa[8];'' creates an array with 8 instances of full adder and the carry chain between adders is connected by bool array ''c''.
