Exercise 5.15: Add

instruction counting

to the register machine simulation. That is, have the machine model

keep track of the number of instructions executed. Extend the machine model’s

interface to accept a new message that prints the value of the instruction

count and resets the count to zero.

练习 5.15：向寄存器机器模拟添加指令计数功能，即让机器模型记录已执行的指令数。扩展机器模型的接口，使其接受一条新消息，用于打印指令计数值并将计数重置为零。
