Decode the following ASCII code: 1000111 1101111 0100000 1000011 1100001 1110010 1100100 1101001 1101110 110001 1101100 1110011 0100001.
What bit position in an ASCII code must be complemented to change the ASCII letter represented from uppercase to lowercase and vice versa?
Internally in a computer, with few exceptions, all computation is done using binary numbers. Output, however, often uses ASCII, which is formed by appending 011 to the left of a BCD code. Thus, an algorithm that directly converts a binary integer to a BCD integer is very useful. Here is one such
