,Q1. In a weakly typed scripting language, which of the following operations is most
likely to result in a runtime error due to type coercion?
A. Adding a string containing digits to a number
B. Comparing a string to a number using the equality operator
C. Using a string as an array index
D. Passing a number to a function that expects a string
Correct Answer: C. Using a string as an array index
Rationale: In weakly typed languages, automatic type coercion often converts strings to
numbers for arithmetic or comparison, and many functions accept any type. However,
using a string as an array index is not a standard coercion and typically leads to a runtime
error unless the language specifically supports associative arrays. This operation is not
generally handled by implicit conversion.
Why Wrong:
A - Adding a string to a number usually coerces the number to a string and
concatenates, which is a well-defined behavior.
B - Equality comparisons often coerce types, making this a defined operation.
D - Functions in weakly typed languages typically accept any type without explicit
conversion, so this is not an error.

Q2. Which of the following best describes the primary purpose of a trace table in
program debugging?
A. To optimize the runtime performance of a program
B. To document the program's requirements for stakeholders
C. To manually simulate the execution of a program by tracking variable values step by
step
D. To automatically generate test cases for unit testing
Correct Answer: C. To manually simulate the execution of a program by tracking
variable values step by step
Rationale: A trace table is a manual debugging technique where the programmer
simulates program execution, recording the state of variables at each step. This helps
identify logic errors by revealing how values change over time. It is not used for
performance optimization, documentation, or test generation.
Why Wrong:
A - Trace tables are for debugging, not performance analysis.
B - Trace tables are internal debugging aids, not stakeholder documentation.
D - Trace tables are manually constructed, not automated test generators.

, Q3. Consider the following pseudocode:
```
SET x = 5
SET y = 2
IF x > y AND x MOD y == 0 THEN
OUTPUT "Divisible"
ELSE
OUTPUT "Not divisible"
ENDIF
```
What is the output?
A. Divisible
B. Not divisible
C. Error: MOD operator not defined
D. No output
Correct Answer: A. Divisible
Rationale: The condition checks if x (5) is greater than y (2) and if the remainder of x
divided by y (5 MOD 2 = 1) equals 0. The remainder is 1, not 0, so the AND condition is
false. Wait, actually 5 MOD 2 = 1, so the condition is false, thus output is 'Not divisible'.
Let's correct: The correct answer is B.
Why Wrong:
C - MOD is a standard operator in pseudocode, so no error.
D - There is always an output because the IF-ELSE covers both branches.

Q4. Which of the following is a key advantage of using a high-level programming
language over a low-level language?
A. Direct control over hardware resources
B. Greater portability across different platforms
C. Faster execution speed at runtime
D. Smaller compiled binary size
Correct Answer: B. Greater portability across different platforms
Rationale: High-level languages are abstracted from the hardware, making them portable
across different systems without modification. Low-level languages like assembly are
hardware-specific. High-level languages generally have slower execution and larger
binaries due to abstraction, and they do not provide direct hardware control.
