EDPT Flowchart Interpretation 4 ā Questions and Answers
Question 1: A flowchart has two parallel branches that both must complete before proceeding. This construct is best described as:
- A sequential process
- A conditional branch
- A parallel or concurrent process (Correct answer)
- A recursive loop
Correct answer: A parallel or concurrent process
Parallel branches represent concurrent processing where multiple paths execute simultaneously before merging.
Question 2: In the following flowchart logic: If A=1 AND B=1 then output 'Both True', else output 'Not Both'. What is the output when A=1 and B=0?
- Both True
- Not Both (Correct answer)
- Error
- No output
Correct answer: Not Both
The AND condition requires both A=1 and B=1; since B=0, the condition is false and 'Not Both' is output.
Question 3: A flowchart processes N items with a nested loop: outer loop runs N times, inner loop runs N times each. What is the total number of inner loop executions?
- N
- 2N
- NĀ² (Correct answer)
- N log N
Correct answer: NĀ²
A nested loop where both loops run N times results in N Ć N = NĀ² total inner loop executions.
Question 4: A flowchart reads numbers and outputs only those that are divisible by both 3 and 5. The decision box should check:
- Number mod 3 = 0 OR Number mod 5 = 0
- Number mod 3 = 0 AND Number mod 5 = 0 (Correct answer)
- Number mod 15 ā 0
- Number > 15
Correct answer: Number mod 3 = 0 AND Number mod 5 = 0
Divisibility by both 3 and 5 requires both conditions to be true simultaneously, requiring AND logic.
Question 5: In a flowchart, what is indicated when a flow line points backward (upstream) to an earlier process step?
- An error in the flowchart
- A loop or repetition structure (Correct answer)
- A branch to a subroutine
- End of process
Correct answer: A loop or repetition structure
A backward-pointing arrow creates a loop, causing earlier steps to be repeated until an exit condition is met.
Question 6: A flowchart tests employee grade: if grade ā„ 90 ā 'A'; else if grade ā„ 80 ā 'B'; else if grade ā„ 70 ā 'C'; else ā 'F'. What letter does a grade of 80 receive?
- A
- B (Correct answer)
- C
- F
Correct answer: B
A grade of 80 fails the first condition (ā„90) but passes the second (ā„80), so it receives a 'B'.
Question 7: A document symbol (a rectangle with a wavy bottom edge) in a flowchart represents:
- A decision
- A printed report or document output (Correct answer)
- A stored data file
- A manual process
Correct answer: A printed report or document output
The document symbol specifically represents a printed report, form, or document that is produced or used.
