Choose all the reasons why programming in assembly code is difficult ....

• There is only a small range of instructions available to achieve even the largest task

• You have to decide how to represent and store ALL the data in the program, even WHERE it is stored in memory

• Difficult to debug a program, as a buggy program usually just crashes the computer

• Difficult to understand what instruction the mnemonics represent
