Solidity - Arithmetic Operators
Addition operator (+) works for Numeric as well as Strings. e.g. "a" + 10 will give "a10".
Example
The following code shows how to use arithmetic operators in Solidity.
pragma solidity ^0.5.0;
contract SolidityTest {
constructor() public{
}
function getResult() public view returns(uint){
uint a = 1;
uint b = 2;
uint result = a + b; //arithmetic operation
return result;
}
}
Run the above program using steps provided in Solidity First Application chapter.
Output
0: uint256: 3
