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

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.
