This is my constructor

constructor (uint256 _initialSupply) {
        ownerOfContract = msg.sender;
        balanceOf[msg.sender] = _initialSupply;
        totalSupply = _initialSupply;
    }

But when I deploy the contract, it gives me the following error:

{ reason: 'missing argument: in Contract constructor',
code: 'MISSING_ARGUMENT', count: 0, expectedCount: 1 }

Upon googling I came to know that constructor and deploy function should have same number of arguments when deploying through hardhat. But what should I pass in deploy()?

When you call Contract.deploy(), you just need to pass the constructor parameters in the order they are declared in your contract, like this:

Contract.deploy(initialSupply), or Contract.deploy("100000000");

If your constructor looked like this: constructor (uint256 _initialSupply, string tokenName)

Then you would deploy it in hardhat like:

Contract.deploy("100000000", "TokenA")
