1. The following function, which computes the area of a triangle, contains two errors. Locate the errors and show how to fix them. (Hint: There are no errors in the formula)

double triangle_area(double base, height)
double product;
{
	product = base * height;
	return product / 2;
}

Answer:

// A type annotation is needed for `height`
double triangle_area(double base, double height)
{
	// The `product` variable declaration was not in the function block.
	double product;
	product = base * height;
	return product / 2;
}

2. Write a function check(x, y, n) that returns 1 if both x and y fall between zero and n - 1 inclusive. The function should return 0 otherwise. Assume that x, y, and n are all of type int

int check(int x, int y, int n) {
	if (x < 0)
}
