An error caused by improper use of program statements.

An error caused by improper use of program statements.

• A. Semantic error
• B. Truncation error
• C. Arithmetic error
• D. Logical error

Answer: (A)

This tests recognizing semantic errors, which happen when the statements in a program are used in a way that doesn’t express the intended meaning. The program may compile and run, but its behavior is incorrect because the way the statements are applied violates what you meant to accomplish. For example, using an assignment where you meant to compare values in a condition changes what the code does, even though the syntax is valid; the logic is simply expressing something different from your intention, which is the essence of a semantic error. This is distinct from a truncation error, which comes from losing precision when converting or restricting data types; an arithmetic error, such as division by zero, involves the math operations themselves; and a logical error refers to a flawed algorithm or incorrect reasoning that yields wrong results even if the statements are used to express a reasonable method.
