Write a C program called velocity. c to do the following activities. • The parent process should read an array (size 6) of double (frequency (1)) from the user
and creates a pipe to do the inter-process communication and then creates a child process
(Child-1).
• Child-1 will calculate the velocity (V) when the wavelength() is 100 m (constant) and write
answers to the pipe. Use the formula is given below;
V = fa
(V=Velocity, f=frequency, 1=wavelength)
. Then the Child-1 creates a new child process (Child-2) and the Child-2 should read values
from the pipe and print them to the screen.​

Fill in the following program so that it will correctly calculate the price of the orange juice the user is buying based on the buy one get one sale.#include //main functionint main() { int cartons; float price, total; //prompt user for input information printf("what is the cost of one container of oj in dollars? \n"); scanf(" [ select ] ["%d", "%c", "%f", "%lf"] ", & price); printf("how many containers are you buying? \n"); scanf(" [ select ] ["%d", "%c", "%f", "%lf"] ", & cartons); if ( [ select ] ["cartons / 2", "cartons % 1", "cartons % 2", "cartons % price", "cartons / price", "cartons / total"] [ select ] ["=", "==", "! =", "< =", "> =", "< "] 0) total = [ select ] ["price * cartons", "cartons * price / 2 + price", "(cartons / 2) * price", "cartons / (2.0 * price)", "(cartons / 2.0) * price + price", "((cartons / 2) * price) + price"] ; else total = ((cartons / 2) * price) + price; printf("the total cost is $%.2f.\n", total); return 0; }
