Final answer:
The statement is false; comments are usually for explaining and documenting code rather than acknowledging others' work. Attribution is secondary and usually handled in separate documentation or specific attribution comments.
Step-by-step explanation:
The statement that comments are used to acknowledge other programmer's code used in a program is False. Comments in programming are primarily used to describe what a block of code is intended to do, explain complex algorithms, provide metadata like creation or modification dates, and clarify the purpose of specific functions or variables for anyone reading the code. They are not typically used for acknowledging the use of other programmer's code; this would more appropriately be handled through documentation, licensing information, or in a README file accompanying the code.
However, it is not uncommon for developers to include attribution comments within the code if they have used a snippet or a technique from another source, as a courtesy or to comply with licensing requirements. But this is not the primary purpose of comments.
