Free Logical Problems MCQs with Answers
519 Logical Problems MCQs from Analytical and Logical Reasoning, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.

Correct answer: 2NF- A. a
- B. not a
- C. a not a
- D. Compile the error Here's what happens:The variable ch is initialized with the character 'a'.The switch statement checks the value of ch.Since ch is 'a', it matches the case 'a' and executes printf("a");.However, there is no break statement after the first case, so the control falls through to the default case.As a result, it also executes printf("not a");.So, the correct output is:(c) a not a
