tmpSum

tmpSum is a variable name commonly used in programming to store a temporary sum during calculations. It is not a built-in function or a specific keyword in most programming languages, but rather a convention adopted by developers for clarity and readability within their code. The name itself, a portmanteau of "temporary" and "sum," clearly indicates its purpose: to hold a sum that is intermediate and likely to be modified or used only within a specific block of code or function.

Developers often employ tmpSum when iterating through lists, arrays, or other data structures to accumulate values. For instance, when calculating the total of all numbers in an array, a variable named tmpSum might be initialized to zero, and then in each iteration of a loop, the current element's value would be added to tmpSum. Once the loop has processed all elements, the final value of tmpSum would represent the total sum.

The use of tmpSum promotes modularity and helps prevent naming conflicts, especially in larger codebases. By using a descriptive, albeit conventional, name, other programmers encountering the code can quickly understand the variable's role without needing extensive comments. While other names like 'runningTotal' or 'accumulator' could also be used, tmpSum remains a widely recognized and understood convention in the programming community.
