As can be seen s.n acts as the loop counter.

Note that a loop counter is sometimes also referred to as a loop iterator.

The cars operated around the loop counter clockwise, and had an Automatic Block Signal system.

A loop counter, however, only provides the traversal functionality and not the element access functionality.

An example of C code involving nested for loops, where the loop counter variables are i and j:

The loop counter is used to decide when the loop should terminate and for program flow to continue to the next instruction after the loop.

Using variant data types as loop counters in Microsoft Visual Basic where an integer type is also available.

Often the instructions in a loop re-use the same register for the loop counter and the offsets of several arrays.

In order to parallelize this loop, a special 'Iterator' class may be used in place of a standard integer looping counter.

Loop counters change with each iteration of a loop, providing a unique value for each individual iteration.

An expression is called manifest if it is computed only from outer loop counters and constants (a more formal definition is given below).

Note that the loop termination condition, here specified as (loop counter expired), can be set to other values including always-true and always-false.

Implementation of with comparable function as in loop clauses; decreases, whereas increases, the loop counter by the value of the (implicit) by-part.

Unlike many other kinds of loops, such as the while loop, the for loop is often distinguished by an explicit loop counter or loop variable.

Some designs, notably some Forth implementations, used two separate stacks, one mainly for control information (like return addresses and loop counters) and the other for data.

In procedural languages it is common to use the subscript operator and a loop counter to loop through all the elements in a sequence such as an array.

In software engineering, a loop counter is the term often used to refer to the variable that controls the iterations of a loop (a computer programming language construct).

Since an XMM register is twice as long as an MMX register, loop counters and memory access may need to be changed to accommodate this.

Such an "increment count and jump" instruction specifies an accumulator, index register, or store location whose contents are to be used as a loop counter (and which will have been initialized by another instruction).

A common identifier naming convention is for the loop counter to use the variable names i, j, and k (and so on if needed), where i would be the most outer loop, j the next inner loop, etc.
