Write c code that does the following: 1. interactively read the coefficients of a quadratic equation and compute the two roots. the program must alert if there is no real root, i. e., read and c of 2 + + c = 0, and compute x = −±√ 2− ; note: a. sqrt() is available in math. h b. for putty/omega server, include -lm while compiling, i. e. gcc -lm myprogram. c c. make sure that you add a routine to check the positiveness of the discriminant using the if statement. show actual runs and examples
