[Solidity] How to receive multiple return values?

This section describes how to receive multiple return values in a function in Solidity.

Syntax

To receive multiple return values in a function in Solidity, do the following.

Describe the data type for the return value in returns, and describe each return value in round brackets (()) in returns.

Note that multiple return values are returned as a single array.

function function name access modifier state modifier returns (return type 1, return type 2, return type 3, ..., return type n) {
    return (return value 1, return value 2, return value 3, ..., return value n);
}

contract Test {
    
    function getMultipleReturnValues() public pure returns(uint, string memory, address) {
        return (1, "solidityrun", address(0)); // [1, "solidityrun", 0x0000000000000000000000000000000000000000] array is returned
    }
