Chapter 2, Problem 1MC

A error does not prevent the program from running, but causes it to produce incorrect results.

1. a. syntax
2. b. hardware
3. c. logic
4. d. fatal

Program Description Answer

The “logic” error causes the program to produce unexpected results, but it will not terminate the program from running.

Hence, the correct answer is option “C”.

Explanation of Solution

Logic error:

Logic error is also called as a bug, which makes a program to operate with the fault, where the program may respond differently and can produce unexpected results.

• In this scenario, the program will work correctly, but will produce output with errors.
• Once the program is in an executable form, the program is tested to check whether it has any logic error.
• The problem with the logic error is that it will not make the program to terminate or crash.
• The logic error will produce wrong output that may not be immediately identified by the programmer.

Explanation for incorrect options:

Syntax:

An error which occurs on the source code of a program is referred as syntax error; because the computer programs strictly follows the syntax rules, if the code fails to prove its language syntax format then the compiler will throw an error.

Hence, the option “A” is wrong.

Hardware:

Hardware error is nothing, but a malfunction of a hardware device which is physically present in the computer.

Hence, option “B” is wrong.

Fatal:

The fatal error is an error that causes a code to abort. When this error occurs, the data in the program may be lost.

Hence, the option “D” is wrong.
