How to use Local Variable for whose values are present till function is executing in solidity ?

pragma solidity ^0.5.0;

contract SolidityTest {

   uint storedData; // State variable

   constructor() public 

{

      storedData = 10;   

   }

   function getResult() public view returns(uint)

{

      uint a = 1; // local variable

      uint b = 2;

      uint result = a + b;

      return result; //access the local variable

   }

}
