Structs

Solidity also supports structs. Here is an example that shows struct syntaxes:

contract sample{     struct myStruct {         bool myBool;         string myString;     }     myStruct s1;     //wherever a struct method is seen a new struct is created. If the struct method is in state than it's stored in storage and if it's found inside function than its stored in memory     myStruct s2 = myStruct(true, ""); //struct method syntax     function sample(bool initBool, string initString){         //create a instance of struct         s1 = myStruct(initBool, initString);         //myStruct(initBool, initString) creates a instance in memory         myStruct memory s3 = myStruct(initBool, initString);     } } 

Note that a function parameter cannot be a struct and a function cannot return a struct.
