A loop control variable is the variable that controls how many times a loop will iterate. It is commonly used in for loops and while loops to specify the number of iterations. A counter (A) is a type of loop control variable that is incremented or decremented on each iteration of the loop. An accumulator (B) is also a type of loop control variable, but it is used to keep a running total of values as the loop iterates. A sentinel (C) is a value used to indicate the end of a sequence of inputs or processing; it is not a loop control variable. Total (D) is a term used to refer to the sum of values or the overall result of a calculation; it is not a loop control variable.
