64. Full Adder

How do you plan to solve it?

// Half Adder primitive
module half_adder (
    input  a, b,
    output sum, carry
);

 assign sum = a ^ b;
 assign carry = a & b;
    
endmodule

// Full Adder using 2 Half Adders
module full_adder_struct (
    input  a, b, cin,
    output sum, cout
); 
wire s0, c0, c1;
half_adder h0(.a(a), .b(b), .sum(s0), .carry(c0));
half_adder h1(.a(s0), .b(cin), .sum(sum), .carry(c1));
or (cout, c1, c0);
    // Write code here


endmodule
