I want a public function to take an array and append it to another array. I am having problems with example.push(_inputArray);

it says example has no function push.

but example.push("Hello") works

As far as I know you can not do what I asked.

instead use a for loop

for (uint i = 0; i < _inputArray; i++) {

        passwordExecutive.push(_inputArray[i]);

    }
