Structs

These constructs can be used to group a set of dissimilar data types under a logical group. These can be used to define new types, as shown in the following example:

pragma solidity ^0.4.0; 
contract TestStruct { 
  struct Trade 
  { 
    uint tradeid; 
    uint quantity; 
    uint price;  
    string trader; 
  } 
 
  //This struct can be initialized and used as below 
 
  Trade tStruct = Trade({tradeid:123, quantity:1, price:1, trader:"equinox"}); 
 
}
