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
    xor X1(sum,a,b);
    and A1(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 psum,pcarry1,pcarry2;
    half_adder ha1(a,b,psum,pcarry1);
    half_adder ha2(psum,cin,sum,pcarry2);

    or or1(cout,pcarry1,pcarry2);


endmodule
