Describe the algorithm for finding the lowest value in an array.

In computer programming, an array is a collection of items stored at contiguous memory locations. The items in an array can be accessed using indices. Array iteration refers to the process of sequentially accessing each element in the array. To find the lowest value within an array, you'll have to iterate over each element, checking them one by one against a known value (initially set to the first element of the array).
To effectively iterate over an array, you'd typically use a loop structure, such as a 'for' loop or 'while' loop. These loops help in running through the array from the first index (usually 0 in zero-indexed languages) to the last index which corresponds to the length of the array minus one. Correct iteration is crucial in many algorithms and understanding how to traverse an array efficiently will strengthen your programming foundation.

In most programming tasks, you'll need to begin by initializing variables; it's a fundamental concept to grasp. Initialization is the assignment of an initial value to a variable. For the task of finding the lowest value in an array, you typically start by setting a variable—let's call it 'min_value'—to the first element of the array. Why the first one? Because before we begin comparing, we assume that the first element might be the lowest, having no other comparisons to refute that. As we progress through the array with our iteration, we continue to compare and potentially reassign our 'min_value' variable to reflect the lowest value encountered.

The core of finding the lowest value in an array lies in the ability to perform comparison operations. These operations let a program decide how to order or evaluate two values, for instance, determining if one number is less than another. In our specific task, during each iteration of the array, we use a comparison operation to see if the current element is less than our 'min_value'. If it is, we then update 'min_value' with this new lower number. By the end of the array iteration, we will have used our comparison operation to iteratively select the smallest value in the entire array.

Behind every algorithm, there is an underlying programming logic that dictates how the process unfolds to achieve the desired goal. For finding the lowest value in an array, the logic is straightforward: we make an assumption (the first element is the lowest), check that assumption against every other element through comparison, and adjust when our assumption is proven wrong. It's this logical flow—initialize, compare, and possibly reassign—that ensures the success of the algorithm. The efficiency and effectiveness of any program deeply depend on the programmer's ability to apply logical constructs to solve problems.
