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 carrt = a & b;
    
endmodule

// Full Adder using 2 Half Adders
module full_adder_struct (
    input  a, b, cin,
    output sum, cout
);
    // Write code here
    assign sum = a ^ b ^ cin;
    assign cout = a & b | b & cin | a & cin ;


endmodule
