64. Full Adder

How do you plan to solve it?

a full adder using 2 half adders and an OR gate

// 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 s,c,d;
    half_adder inst1(a, b, s, c);
    half_adder inst2(s, cin, sum, d);
    assign cout = c|d;


endmodule
