write a calculator program to compute math expressions using Linux IPCs (Inter-process communication) - program needs to fork() as many times as needed and use pipes to communicate to children. Equation specified in the first line of the data file will determine this setup. Once the setup is done, parent task reads the data from the data file and pumps into various pipes in parallel and results come back to the main task using another pipe. add, subtract, multiply

Create a function called quadform( ) that takes as input the coefficients of the quadratic equation (a, b,c) and returns the two distinct real roots (x1,x2) as output, if they exist. in addition, the function returns a message (flag) that informs the user if an error occurred when trying to find two distinct real roots. the possible errors are: (1) "only one root is found"; (2) "imaginary roots are found"; (3) "any value of x is a solution"; (4) "no zeroes exist." if no errors occur, then flag should be "no errors".
