Question

In a(n) ____ check, the programmer "walks" through the program design, keeping track of the values of any loop counters and other variables in a tracing table to ensure the program does what it is intended to do?

1) Syntax
2) Logic
3) Debugging
4) Testing

Answer 1

A Logic check is a manual review process where a programmer simulates the program's execution to identify logical errors, ensuring that the program functions as intended and differs from syntax errors or trial-and-error problem-solving.

Step-by-step explanation:

In the context of programming, the scenario described in the question refers to a Logic check. This type of check involves the programmer methodically going through the program design, or code, to verify that all parts of the code operate as intended. To do this, they may use a technique known as desk-checking where they simulate the execution of the program manually, tracking the values of variables and the outcomes of conditional statements or loops in a tracing table. This practice helps in identifying any logical errors that could cause the program to behave incorrectly, such as getting stuck in an infinite loop or producing an incorrect output.

While syntax refers to the rules that define the structure of the code, a logic check is more concerned with the flow and algorithms within the program. This process allows for the identification and correction of errors that are not necessarily syntax errors but can lead to unexpected behaviour or incorrect results. It's a step in the development process that's essential before comprehensive testing can occur, which is often automated and more rigorous. It also differs from trial and error, which is a less systematic approach that involves attempting multiple solutions until finding one that works.
