Question

How do you know whether a computer program has a bug?

(A) By compiling the program and checking for syntax errors.
(B) By running the program and checking for logical errors.
(C) Both (A) and (B).
(D) None of the above.

Answer 1

In order to determine whether a computer program has a bug, you need to perform several steps: compiling the program and checking for syntax errors, as well as running the program and checking for logical errors.

Step-by-step explanation:

In order to determine whether a computer program has a bug, you need to perform several steps:

1. By compiling the program and checking for syntax errors: When a program is compiled, the compiler analyzes the code for any syntax errors, such as missing semicolons or misspelled keywords. If the program contains syntax errors, it will not compile and you will receive error messages highlighting the issues.
2. By running the program and checking for logical errors: After a program has been successfully compiled, you can run it and carefully observe its behavior. If the program produces incorrect results or crashes unexpectedly, it is likely that there are logical errors (bugs) in the code.

Therefore, the correct answer is option (C) Both (A) and (B), as both compiling the program and running it are necessary steps to identify bugs.
