Multiple Return Values in Solidity

This multipleReturns function is the first example we've seen that returns multiple values. Let's look at how to handle them:

function multipleReturns() internal returns(uint a, uint b, uint c) {
  return (1, 2, 3);
}

function processMultipleReturns() external {
  uint a;
  uint b;
  uint c;
  // get all A,B,C
  (a, b, c) = multipleReturns();
}


function getLastReturnValue() external {
  uint c;
  (,,c) = multipleReturns(); //only C
}
