Understanding LMC Assembly Language

What is the primary function of the accumulator in the LMC?

• To store the program counter

• To hold intermediate arithmetic and logic results

• To manage input and output operations

• To store the address of the next instruction

Which LMC instruction is used to read input from the user?

• OUT

• ADD

• INP

• SUB

In LMC, which instruction is used to output data to the user?

• STA

• LDA

• INP

• OUT

What does the LMC instruction `ADD` do?

• Subtracts a value from the accumulator

• Adds a value to the accumulator

• Multiplies a value with the accumulator

• Divides the accumulator by a value

Which instruction in LMC is used to subtract a value from the accumulator?

• ADD

• SUB

• STA

• LDA

What is the purpose of the `BRZ` instruction in LMC?

• Branch if the accumulator is zero

• Branch if the accumulator is negative

• Branch if the accumulator is positive

• Branch unconditionally

Which LMC instruction is used to store the value from the accumulator into a specific memory location?

• LDA

• STA

• ADD

• SUB

In LMC, what does the `HLT` instruction do?

• Halts the program execution

• Loads a value into the accumulator

• Outputs the value in the accumulator

• Reads input into the accumulator

Which instruction in LMC is used to load a value from a specific memory location into the accumulator?

• STA

• LDA

• ADD

• SUB

What is the role of the program counter in LMC?

• To store the current instruction

• To keep track of the next instruction to be executed

• To manage input and output operations

• To hold arithmetic results
