Article Introduction：There is no function named "sum" in the C language standard library. "sum" is usually defined by programmers or provided in specific libraries, and its functionality depends on the specific implementation. Common scenarios are summing for arrays, and can also be used in other data structures, such as linked lists. In addition, "sum" is also used in fields such as image processing and statistical analysis. An excellent "sum" function should have good readability, robustness and efficiency.
