Which instruction would increment Data Register 10 by two?

• A. R[10] += 1
• B. R[10] = R[10] * 2
• C. R[10] = R[10] + 2
• D. ADD R[10], 2

Answer: (C)

Incrementing a data register means adding a specified value to the current value stored in that register. In this instance, to increment Data Register 10 by two, the instruction must clearly state that two is to be added to the existing value in that register. The instruction that achieves this is the one that explicitly states "R[10] = R[10] + 2." This conveys the meaning that the current value of Data Register 10 is first retrieved, then two is added to that value, and the result is stored back in Data Register 10. This operation effectively increases the value in the register by the desired amount of two. While other options may manipulate the register in various ways, they do not perform the specific task of incrementing the register's value by two. For instance, one option suggests increasing it by 1, another option multiplies the value by two, and yet another might involve an addition but isn't directly configured to achieve the goal of incrementing by two. Hence, the correct instruction clearly outlines the addition of two to the current value, making it the appropriate choice for this task.
