Study the following program and answer the questions: #include #include int uig; int ig = 5; int func() { return 0; } int main() } int local; int *ptr; ptr (int *)malloc(sizeof(int)); = printf("An address from BSS: %p ", &uig); printf("An address from Data segment: %p ", &ig); printf("An address from Code segment: %p ", &func); printf("An address from Stack segment: %p ", &local); printf("An address from Heap: %p ", ptr); printf("Another address from Stack: %p ", &ptr); free(ptr); return 0; Questions: Examine last line of output. It shows another address from stack. 1. Why &ptr is in the stack segment? 2. Why distance is 4 byte between local and &ptr? 3. Why &ptr is less than &local?
