Write LMC code that will reset the value of the memory location labelled total to zeroand then stop the program

Sure, here is the LMC (Little Man Computer) code:

      LDA total
      SUB total
      STA total
      HLT
total DAT

Here's a step-by-step explanation:

1. LDA total: This line loads the value at the memory location labelled 'total' into the accumulator.
2. SUB total: This line subtracts the value at the memory location labelled 'total' from the value currently in the accumulator. Since we just loaded the value from 'total' into the accumulator, this will result in zero.
3. STA total: This line stores the value currently in the accumulator (which is now zero) back into the memory location labelled 'total'.
4. HLT: This line halts the program.
5. total DAT: This line declares a memory location labelled 'total'. The DAT instruction is used to declare a variable. In this case, it's not initialized with any value.
