Suppose that the input stream stdin contains the (invalid) IP address: 298.173.41.142 Assuming that the variables A and B are declared as ints, which of the following code fragments will correctly read the second part of the IP address (173) into the variable B? a. scanf("%d", &A);
char ch = fgetc(stdin);
scanf("%d", &B);

b. scanf("%d %d", &A, &B);

c. scanf("%d.%d", &A, &B);
