+ *  ch. (Hint: assuming each character is stored using 8 bits, start by using the hexadecimal mask 80,
+ *  which corresponds to the binary number 10000000. If the result of the masking operation is 0; else
+ *  display a 1. Then shift the mask one place to the right and examine the next bit, and so on until
+ *  all bits in the variable ch have been processed
