Quick C pointers review:

Note to students: feel free to download the code from here:

unsigned char* x = (unsigned char*)0x8;
unsigned int*  y = (unsigned int*)0x8;

printf("x     = %p\n", x);      // will print "0x8"                                
printf("x + 1 = %p\n", x + 1);  // will print "0x9"                                
printf("y + 1 = %p\n", y + 1);  // will print "0xC", why?   

printf("*x   = %d\n", *x);      // will print 32                                    
printf("x[0] = %d\n", x[0]);    // will print 32                                    
printf("x[1] = %d\n", x[1]);    // will print 48                                    
printf("y[0] = %u\n", y[0]);    // will print a big number. Why???     

printf("*x   = %d\n", *x);      // will print 32                                    
printf("x[0] = %d\n", x[0]);    // will print 32                                    
printf("x[1] = %d\n", x[1]);    // will print 48 

printf("y[0] = %u\n", y[0]);    // will print a big number. Why???                  
                                // (Hint: you may want to read how                  
                                // integers are stored in an
