Write C code that does the following:1. Interactively read the three coefficients of a quadratic equation and compute the two roots. Read a, b, c of

a x² + b x + c = 0,

and compute

x =

b

b2 4 a c

2 a

.

Note: sqrt is available in math.h. You need to compile the program with "-lm" option, i.e.

gcc -lm myprogram.c 

Make sure that you add a routine to check the positiveness of the discriminant using the if statement. Show actual runs and examples.2. Interactively read temperature in Celsius and convert it to Fahrenheit. Note

C = (F 32 )

59

.

Example:

$ a.out Enter temperature in C = 29 It is 84.2 degrees in Fahrenheit.
