This program #1, you are required to develop a program that takes a numeric input (0 to 63) and converts it to binary. You will use the LMC (Little Man Computer) for this program. The LMC is a decimal only machine and outputs 3 digits (000 - 999). Since 2^6 is 64 combinations, 2 numbers will be output.
For example, a 24 is entered, the first digit out is 011, and the second is 000. Another, 33 input yields a 100 001. You can have an infinite loop or a stop input. The output has leading zero suppression. So a blank is considered a zero Here are the starting lines of code for a solution. Please study them and let me know if you have any questions. #line_label instruction value comment
