Engineering Computer Science Problem Solving with C++ (10th Edition)

(This Project requires that you know some basic facts about complex numbers, so it is only appropriate if you have studied complex numbers in some mathematics class.) Write a C++ program that solves a quadratic equation to find its roots. The roots of a quadratic equation ax 2 + bx + c = 0 (where a is not zero) are given by the formula (−b ± sqrt(b 2 − 4ac)) / 2a The value of the discriminant (b 2 − 4ac) determines the nature of roots. If the value of the discriminant is zero, then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots. The program takes values of a, b, and c as input and outputs the roots. Be creative in how you output complex roots. Include a loop that allows the user to repeat this calculation for new input values until the user says she or he wants to end the program.

(This Project requires that you know some basic facts about complex numbers, so it is only appropriate if you have studied complex numbers in some mathematics class.)

Write a C++ program that solves a quadratic equation to find its roots. The roots of a quadratic equation

ax² + bx + c = 0

(where a is not zero) are given by the formula

(−b ± sqrt(b² − 4ac)) / 2a

The value of the discriminant (b² − 4ac) determines the nature of roots. If the value of the discriminant is zero, then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots.

The program takes values of a, b, and c as input and outputs the roots. Be creative in how you output complex roots. Include a loop that allows the user to repeat this calculation for new input values until the user says she or he wants to end the program.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
