Answers and Descriptions
Answer:
1 2 3 4 5 6 7 8 9 10 | INPUT number IF number > 0 THEN IF number MOD 2 = 0 THEN OUTPUT "Positive and even" ELSE OUTPUT "Positive but odd" ENDIF ELSE OUTPUT "Not positive" ENDIF |
Description: Nested If statements check for positive and even conditions, demonstrating layered decision-making in programming.
Answer:
1 2 3 4 5 6 | FOR i = 1 TO 3 FOR j = 1 TO 3 OUTPUT "*" + " " ENDFOR OUTPUT newline ENDFOR |
Description: Nested loops iterate over rows and columns to print a grid, testing the ability to manage multiple iteration levels.
Answer:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | INPUT n isPrime = TRUE IF n MOD 2 = 1 THEN FOR i = 2 TO SQRT(n) IF n MOD i = 0 THEN isPrime = FALSE BREAK ENDIF ENDFOR IF isPrime THEN OUTPUT "Prime and odd" ELSE OUTPUT "Odd but not prime" ENDIF ELSE OUTPUT "Not odd" ENDIF |
Description: This combines selection (odd check) and iteration (prime check), testing complex nested logic integration.
Answer: Index, contiguous locations, random access.
Description: A one-dimensional array stores elements linearly, accessed via indices (starting at 0), in contiguous memory, supporting efficient random access.Answer:
1 2 3 4 5 6 | DECLARE array[5] AS INTEGER array[0] = 2 array[1] = 4 array[2] = 6 array[3] = 8 array[4] = 10 |
Description: This pseudo code declares and assigns even numbers to an array, demonstrating basic array manipulation skills.
