The Concept Isolating and identifying problems in programs is a crucial skill for programmers. This set of exercises is designed to give you an opportunity to practice these skills. Obser this attempt to implement the quadratic formula: 7 double a, b, c, x1, x2, discriminant; 8 9 cout > a >> b >> C; 10 11 12 13 14 15 16 17 //Expected value: 25 discriminant = b + b - 4 * a * a; x1 = (-B + sqrt(discriminant)) / 2. a; X2 = (-b - sqrt(discriminant)) / 2. a; 18 19 20 // Expect -4 cout
