Directions: use only the signal mechanism system calls don’t use ( wait() or pipe() )in this problem. You can still read/write from/to a file.

A. File I/O using C library functions File I/O in C is achieved using a file pointer to access or modify files. Processing files in C is a four-step process: o Declare a file pointer. o Open the desired file using the pointer. o Read from or write to the file and finally, o Close the file. FILE is a structure defined in <stdio.h>. Files can be opened using the fopen() function. This function takes two arguments, the filename and...
