What will the output of the following program be?

#include #include #include int value = 5; int main() { pidtpid; pid = fork(); if (pid == 0) { /* child process */ value += 15; return 0; } else if (pid > 0) { /* parent process */ wait(NULL); printf("PARENT: value = %d",value); /* LINE A */ return 0; } }

****************************************************************

What happen if we alter the previous program to copy a pointer instead? Does the output change?

#include #include #include #include int main() { int* value = (int*)malloc(sizeof(int)); *value = 5; pid_t pid; pid = fork(); if (pid == 0) { /* child process */ *(value) += 15; return 0; } else if (pid > 0) { /* parent process */ wait(NULL); printf("PARENT: value = %d",*value); /* LINE A */ return 0; } }
