64. Full Adder

How do you plan to solve it?

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

    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
);
    // Write code here
    wire h1_sum,h1_carry,h2_carry;

    half_adder h1(a,b,h1_sum,h1_carry);
    half_adder h2(h1_sum,cin,sum,h2_carry);

    assign cout = h2_carry|h1_carry;


endmodule
