NO LINKS<br />Write a C program called velocity. c to do the following activities.<br />• The parent process should read an array (size 6) of double (frequency (1)) from the user<br />and creates a pipe to do the inter-process communication and then creates a child process<br />(Child-1).<br />• Child-1 will calculate the velocity (V) when the wavelength() is 100 m (constant) and write<br />answers to the pipe. Use the formula is given below;<br />V = fa<br />(V=Velocity, f=frequency, 1=wavelength)<br />. Then the Child-1 creates a new child process (Child-2) and the Child-2 should read values<br />from the pipe and print them to the screen.​
