The correct answer is: C. Accumulating.

Accumulating is the process of adding a number to the value stored in a variable. It is often used in computer programming to keep track of a running total. For example, if you wanted to keep track of the number of times a user clicked on a button, you could use an accumulator to store the total number of clicks.

The other options are incorrect because they do not accurately describe the process of adding a number to the value stored in a variable.

• Counting is the process of determining how many times something occurs. For example, you might count the number of students in a class.
• Updating is the process of changing the value of a variable. For example, you might update the value of a variable to reflect the current time.
• Decrementing is the process of decreasing the value of a variable by 1. For example, you might decrement the value of a variable to keep track of the number of items in a list that have been removed.
