Here's a C/C++ program that converts decimal numbers ranging from 0 to 99,999 to binary and binary coded decimal (BCD) formats. Using a simple algorithm in conjunction with pointer arithmetic and bitwise shifting increases the conversion speed without introducing excessive memory overhead and programming complexity. When decimal numbers are within the range of 0 to 9, their binary and BCD representations are identical, requiring only four bits (0000 to 1001). When the numbers are within the range of 10 to 19, the binary representation varies between four and five bits, such as 1010 to 10011. The BCD representation uses eight bits, such as 0001 0000 to 00011001.
