Knowing more about the structure of an array
We have already briefly touched on the topic of structures. Structures help in defining custom user-defined data structures. Structures help to group a multiple variables of different data types into a single type. A structure does not contain any programming logic or code for execution; it just contains a variable declaration. Structures are reference types and treated as complex types in Solidity.
Structures can be defined as state variables, as shown in the next code snippet. A struct composed of the string, uint, bool, and uint arrays is defined. There are two state variables, which are in the storage location. While the first stateStructure1 state variable is initialized at the time of declaration, the other stateStructure1 state variable is left to be initialized later within a function.
A local structure at the memory location is declared and initialized within the getAge function. Another structure is declared that acts as...
