QUESTION 1

Write the function called plus10() that gets an integer x as parameter. It simply returns the value x+10. Then, from the main function, test your new function by calling it and outputting its value to screen.

QUESTION 2

Write the function called damage() that gets three parameters:

· int lowDamage;

· int highDamage;

· double accuracy;

The value of accuracy is a decimal that expresses the percentage chance of getting a hit. So, if the accuracy is 0.8, then there will be a hit 80% of the time and a miss 20% of the time. If a miss occurs, the function should simply return -1.

If a hit occurs, a random value between lowDamage and highDamage is returned.

You should test your function with the following main function:

public static void main(String[] args)

{

int linkDamage = damage(4, 10, 0.6);

if (linkDamage == -1)
System.out.println("Link missed.");

else

System.out.println("Link did " + linkDamage + " dmg.");

int ganonDamage = damage(10, 20, 0.3);

if (ganonDamage == -1)

System.out.println("Ganon missed.");

else

System.out.println("Ganon did " + ganonDamage + " dmg.");

}
