Write a C program, to solve the quadratic equation a x2 + b x + c = 0 of given coefficients a, b and c. When running the program, it prompts for the input of coefficients a,b,c as floating numbers. After inputting three floating numbers, it computes and prints out the solutions, then prompts for another round of input. Your program will quit when getting input 0,0,0. Your program should handle four situations: (1) a=0, not a quadratic equation; (2) b2 - 4ac = 0, the equation has two equal roots; (3) b2 - 4ac < 0, the equation has complex roots; (4) b2 - 4ac > 0, the equation has distinct real roots. Your program should be robust for invalid inputs.
