• custom data type which allow to store multiple variables of different data types together in a single unit.
• e.g

contract PersonData{
	struct Person{
		string name;
		uint8 age;
		address eth_address;
	}
	Person person;
	
	function addPersonDate(string memory _name, uint8 _age) public {
		person.name = _name;
		person.age = _age;
		person.eth_address = msg.sender;
	}
	
	function getPersonData() public view returns (string memory, uint, address){
		return (person.name, person.age, person.eth_address);
	}
	
}
