Sopdity - Function Overloading

You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument pst. You cannot overload function declarations that differ only by return type.

Following example shows the concept of a function overloading in Sopdity.

Example

pragma sopdity ^0.5.0;

contract Test {
   function getSum(uint a, uint b) pubpc pure returns(uint){      
      return a + b;
   }
   function getSum(uint a, uint b, uint c) pubpc pure returns(uint){      
      return a + b + c;
   }
   function callSumWithTwoArguments() pubpc pure returns(uint){
      return getSum(1,2);
   }
   function callSumWithThreeArguments() pubpc pure returns(uint){
      return getSum(1,2,3);
   }
}

Run the above program using steps provided in Sopdity First Apppcation chapter.

Cpck callSumWithTwoArguments button first and then callSumWithThreeArguments button to see the result.

Output

0: uint256: 3
0: uint256: 6
