a. You are working on a project that contains the following code: int w, x, y, z; scanf("%d &x, &y); printf("x = %d, .y = %d ", x, y); z = first_function(x, y); printf("z=%d ", z); w = second function(x, y, z); printf("w = %d " W); T When you run the code, you get the following output: x = 1, y = 2 Segmentation Fault A classmate points out that the problem must be with first_function since the program crashes before it can print anything else. Are they correct? Explain. [4 pts] b. The following code crashes with a segfault. Why? [3 pts] printf("p = %d ", *p); c. The following code crashes with a segfault. Why? [4 pts] #include #include struct bank_record { int id; double balance; }; int main (void) { } struct bank_record *record; record->id = 3; record->balance = 500.65; printf("Record %d balance: %.2f ", record->id, record->balance); return 0;
