Analysis of Identifiers in Source Code

Identifiers such as variable names and function names in source code are important information to understand code. The way of naming for identifiers and the length of identifiers affects on code understandability, and thus, it is guessed that they affects on software quality. In this study, we investigate the relationship between the length of identifiers and software faults in a software module. The results show that there is a certain relationship between the length of identifier and existence of software faults.
