main (int argc, char *argv) forkthem (5) void forkthem (int n) f if (n>O) f fork () forkthem (n-1); 9. Consider the following program: main (int argc, char*argv) ( int child -fork (): int x# 5; if (child0) f x += 5; ) else ( child fork (); x +10; if (child) f x 5 How many different copies of the variable x are there? What are their values when their process finishes
