Given a triangle with a base b and a height h its area is A = bxh. The following piece of C code which computes the area of a triangle contains errors. Locate the errors and show how to fix them. [5] float area_of_triangle (float base, height) float product; { product = base+height return (product/2 } 9. The following piece of code must print the number of negative values in the array Integer. Locate the errors and show how to fix them. [5] = int Integer[] = {-5,1,3,7,8,-1,-3,-7,3,10]; int i; n=0; while (n <= 10) { n += (Integer < 0)? 1:0; i; } printf("%d ", n); 4
