WebState variables. Variables in programming refer to storage location that can contain values. These values can be changed during runtime. The variable can be used at multiple places within code and they will all refer to the value stored within it. Solidity provides two types of variable—state and memory variables.

WebHere we'll consider only the composite data struct and arrays. In a solidity smart contract, struct and array are by default assigned storage instead of memory, even when they are local to functions. While a struct or array is used as a parameter or a local variable in a function, declare them as memory variables. WebSep 6, 2024 · Solidity can handle different types of data and provides different types of variables to handle each type. When you define variables, you have to specify the datatype of the variable.
