Solidity code to change value of name

0 votes

I am following tutorial and I have two tasks to do.

  1. setName function should allow setting value of name
  2. increaseCounter should increase the counter by 10 whenever it is called

I have completed writing the other methods and it works fine but I’m stuck with this. Can someone tell how can I implement this?

Try this for setName:

function setName(string _name) public {

    name = _name;

  }

And this for increaseCounter:

function increaseCounter() public {

    counter += 10;

  }

This should work.
