Variables & Scopes

We can divide variables in Solidity into three classes:

Copy

// 1. Fixed Size Types
bool isTrue = true;
int8 number1 = 12;
uint number2 = 12;
address address = 0x.....;
bytes32 name1 = "name1";

// 2. Dynamic Size Types
string name2 = "name2";
bytes name1 = "name1";
uint[] array = [1,2,3,4,5];

mapping(uint => string) list1;
list1[3] = "value3";

mapping(uint => address) list2;
list2[4] = address;

mapping(uint => Human) list3;

// 3. User Defined Value Types
struct Human {
  uint ID;
  string name;
  string surname;
  uint age;
  address address;
}

Human person1;
person1.ID = 2121212212121;
person1.name = "firstname";
person1.surname = "lastname";
person1.age = 25;
person1.address = 0x.....;


enum trafficLights {
  RED,
  YELLOW,
  GREEN
}
