How do I use a button to increase the value of a slider in Unity?

I'm new in Unity and I don't know how to click a button and increase the value of a slider.

I have created a slider and its value decreases over time. Now I want to increase that value every time I click a button.

public class BarraAlimento : MonoBehaviour
{
  public const float alimentoMax = 100f;
  public float alimento;
  public Slider barraAlimento;

  void Start()
  {
    alimento = alimentoMax;
  }

  void Update()
  {
    barraAlimento.value = alimento;

    if (alimento <= 0)
    {
      alimento = 0;
    }
    else if (alimento > 0)
    {
      alimento -= Time.deltaTime;
    }
  } 
}

That's the script of the slider, but I don't know how to do the button one.

You just need to declare a button and get the onClick event. After that, increase the value as you see fit.

  public Button _yourButton;


    void Start()
    {
        alimento = alimentoMax;
      _yourButton.onClick.AddListener(ButtonClicked);

    }

    void ButtonClicked()
    {
        //increase your value as you wish
        alimento += 1;
    }
