How to initialize an array?

ThePiachu

I want to initialize an array in a Solidity contract and I can't seem to figure out what's the proper syntax for it. A simple approach like:

contract Test { string32[] test = {"A", "B"}; }

gives an error of:

:2:23: Error: Expected primary expression. string32[] test = {"A", "B"}; ^

GeorgeHallam

C++ syntax should be correct.

See more in the tutorial:

Hope that helps!

Inline-initializing arrays is not possible yet. Also arrays stored in memory cannot be dynamic.

@chriseth I just tried dynamic arrays in storage and in doesn't seem to be working either. What is wrong in following example contract? Thx

contract foo {
 struct StackItem {
   uint value;
 }

StackItem[] stack;

function push (uint value) {
  StackItem item = stack[stack.length++];
  item.value = value;
}

function pop () returns (uint) {
  StackItem item = stack[stack.length--];
  return item.value;
}

function stacksize()  returns (uint) {
   return stack.length;
}
}
