Functions
static int	count_bits (int v)
static void	usage (void)
int	main (int argc, char *argv[])

Detailed Description

Study the code in main to understand how to determine the number and types of operands a particular LC3 instruction has. This information is encoded in a data structure defined in lc3.h This code is a subset of the operations you will need to do when writing the assembler.
