Question 54

A compiler checks source code for errors before translating.

A compiler plays a crucial role in the programming process by analyzing the source code for any errors and ensuring that it is syntactically correct before translating it into machine code. This step is essential for preventing runtime errors and improving the overall efficiency of the program.

A) It converts instructions one statement at a time when the program is run.

This option describes the function of an interpreter rather than a compiler. An interpreter translates code one statement at a time during execution, which is different from a compiler's approach of translating the entire source code into machine code before execution.

B) It stores and manages data and develops data-driven reports.

This option is related to data management systems rather than compilers. Compilers do not store or manage data; their primary function is to translate source code into executable code, not to handle data storage or reporting.

C) It checks source code for errors before translating.

This option accurately describes a compiler's role in programming. Before the actual translation of the code into machine language, a compiler checks the source code for syntactical and semantic errors, ensuring that the code is valid and can be executed correctly.

D) It manages computer hardware and software resources and provides common services for computer programs.

This statement refers to the operating system rather than a compiler. While compilers are involved in the development of programs, they do not manage hardware or software resources; that responsibility lies with the operating system.

Conclusion

The correct answer, C, highlights the compiler's essential function of error-checking before translation, which is critical for ensuring code quality and performance. In contrast, options A, B, and D misrepresent the compiler's role or relate to different aspects of computing, thus confirming that C is the only accurate choice.
