Consider the following pseudocode, which you may assume compiles and runs:

int c = 7 // global variable

int main()

{

pid_t pid = fork();

c++;

if(pid == -1)

exit(-1);

else

if(pid == 0)

c += 3;

printf("I am the parent, c is %d ", c);

else

c += 4;

printf("I am the child, c is %d ", c);

}

a. What is the output?

b. Is any other output possible? Defend your answer.
