I am trying to execute the following example listed in the documentation using solidity 0.4
pragma solidity ^0.4.0;
contract C {
uint[] data1;
uint[] data2;
function appendOne() {
append(data1);
}
function appendTwo() {
append(data2);
}
function append(uint[] storage d) {
d.push(1);
}
}
But I get the error:
Error: Location has to be memory for publicly visible functions (remove the "storage" keyword).
When I remove the storage keyword I get another error:
Error: Member "push" is not available in uint256[] memory outside of storage.
d.push(1);
Any solution?
