i have compiler my code through remix… but when i try to verify it on eth scan it gives me following errors

Error! Unable to generate Contract ByteCode and ABI

here is my code

     pragma solidity ^0.5.0;


    contract IBEP20 {
    function totalSupply() public view returns (uint);
    function balanceOf(address tokenOwner) public view returns (uint balance);

    function transfer(address to, uint tokens) public returns (bool success);
    function approve(address spender, uint tokens) public returns (bool success);
    function transferFrom(address from, address to, uint tokens) public returns (bool success);

    event Transfer(address indexed from, address indexed to, uint tokens);
    event Approval(address indexed tokenOwner, address indexed spender, uint tokens);
    }


     contract SafeMath {
     function mul(uint256 a, uint256 b) internal pure returns (uint256 c) {
    if (a == 0) {
      return 0;
    }
    c = a * b;
    assert(c / a == b);
    return c;
  }

     function div(uint256 a, uint256 b) internal pure returns (uint256) {
    return a / b;
  }

     function sub(uint256 a, uint256 b) internal pure returns (uint256) {
    assert(b <= a);
    return a - b;
  }

    c = a + b;
    assert(c >= a);
    return c;
  }
}


    contract MONK is IBEP20, SafeMath {

Hi @coderbang1,

Check that you are using the same Solidity compiler version and optimization. You have a flattened contract, so if it deploys via Remix then you should be able to verify.

thank you… it worked
