Consider the following C program:  #include #include int g1 = 42; int g2; static int sg = 7; void foo(int n) { int local = 5; static int sLocal = 100; int *p = (int*)malloc(n * sizeof(int)); p[0] = g1 + local; printf(“%d\n”, p[0]); free(p); } int main(int argc, char *argv[]) { int x = 10; foo(4); return 0; } Where are the variables x, local, and parameter n stored?

Consider:  #include #include #include int main() { pid_t pid = fork(); if(pid == 0) { printf(“Child exiting\n”); exit(0); } else { sleep(10); printf(“Parent exiting\n”); } return 0; } During the 10-second sleep period, what is the state of the child process?

A researcher observes children in a classroom during their first year of school. While observing, she scores the children on their behaviors. For instance, she assigns them scores on focus and activity level. Then, she examines whether their scores on these items accurately identify which students will be diagnosed with ADHD by the end of grade school. If the researcher’s behavioral observations accurately identify which students get diagnosed at a later point with ADHD, this means her results have what type of validity?
