Which type of error can usually be found during testing and debugging of the program?

Logic errors are indeed often identified during the testing and debugging phases of program development. These errors occur when the program runs without producing any syntax errors, meaning the code is correctly formed and compiles successfully. However, the output is not what the programmer intended because the logic driving the program's flow or decision-making is flawed.

During testing, various input scenarios are run to verify that the functions and features work as expected. When the results do not match the expected outcomes, it indicates there is an issue with the logic used in the code. Debugging tools can help trace through the program's execution to find where the incorrect logic is causing unexpected results, making it easier to isolate and correct these types of errors.

In contrast, syntax errors occur during compilation, preventing the program from running at all, while resource errors often relate to issues like memory allocation that also may not be discovered until runtime. Execution errors may occur while a program is running due to environmental factors or unexpected conditions, but logic errors specifically pertain to flaws in the decision-making processes and are thus most relevant during testing and debugging.
