Write a C program with the following characteristics:

It has a global array of 10 integers. When it starts running, the main function initializes the array elements to numbers from 1 to 10. It creates a child process, which changes every number of the array to its squared value. The child prints the new values of the array. Before the parent process creates the child, it prints the elements of the array. The parent process prints the values of the array another time after the child finishes. Write and explain the output of this program.
