Return argument type struct Details.Prosumer storage ref is not implicitly convertible to expected type (type of first return variable) uint256

Question

Prosumer[] public ProsumeArray;

struct Prosumer{
    uint ProsumerID;
    uint Pros_power;
    uint per_unit_rate;
}

function setPros(uint ProsumerID, uint Pros_power,uint per_unit_rate)public {
    Prosumer memory newProsumer=Prosumer({
        ProsumerID: ProsumerID,
        Pros_power: Pros_power,
        per_unit_rate: per_unit_rate
    });
    ProsumeArray.push(newProsumer);
}

function ChoosePro(uint n) public view returns(uint ){
    return ProsumeArray[n];
}

Answer 1

What are you trying to return?

it seems you are trying to return the struct Prosumer in that case your return type should be Prosumer you can see in the following code:

 function ChoosePro(uint n) public view returns(Prosumer memory){
    return ProsumeArray[n];
 }
