1)What does the following code print out? (hint: run the code and analyze the output, what is the for loop doing?)

int f = 0, g = 1;

for (int i = 0; i <= 15; i++) {

System.out.println(f);

f = f + g;

g = f - g;

}

Write a program that uses a for loop. With the loop, make the variable x go from -10 to 10, counting by 0.5. (This means that x can't be an int.) Inside the body of the loop, make another variable y become the current value of x squared. Then display the current values of both x and y
