How can I increment a variable without exceeding a maximum value?

Question

I am working on a simple video game program for school and I have created a method where the player gets 15 health points if that method is called. I have to keep the health at

Answer 1

I am just going to offer a more reusable slice of code, its not the smallest but you can use it with any amount so its still worthy to be said

health += amountToHeal;
if (health >= 100) 
{ 
    health = 100;
}

You could also change the 100 to a maxHealth variable if you want to add stats to the game your making, so the whole method could be something like this

private int maxHealth = 100;
public void heal(int amountToHeal)
{
    health += amountToHeal;
    if (health >= maxHealth) 
    { 
        health = maxHealth;
    }
}

EDIT

For extra information

You could do the same for when the player gets damaged, but you wouldn't need a minHealth because that would be 0 anyways. Doing it this way you would be able to damage and heal any amounts with the same code.
