Consider the following C program that manipulates newly created file named foo.txt. Write the contents of foo.txt after its execution.

int main(int argc, char *argv[])

{ close(STDOUT_FILENO);

int f = open(“foo.txt”, O_CREAT|O_WRONLY|O_TRUNC, S_IRWXU);

assert (f >= 0);

int rt = fork();

if (rt == 0)

{ write(f, “Child here!\n”, 20); printf(“Child terminates.\n”);

}

else if ( rt > 0)

{

(void) wait(NULL); write(f, “Parent here!\n”, 21);

printf(“Parent terminates.\n”);

}

return 0;

}

readEmpFromFile Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee).
