Question

Consider the following program:
def main() :
   a = 5
   print(doubleIt(a))
def doubleIt(x) :
   return x * 2
main()
What output is generated when this program is run?

The question presents a small Python-like program and asks what output appears when it runs. We will evaluate each answer choice by tracing the flow of the code.
Option 1: 2
This would correspond to a result of halving or otherwise modifying the value by a factor of 2 before printing. However, in the code, the value 5 is passed to doubleIt, and there is no operation that would reduce it to 2. Therefore, printing 2 is incorrect given the actual function behavior.
Option 2: 5
This would indicate that the value is unchanged by the function call. But the function doubleIt multiplies its argument by 2, so the value sent back to the caller should be 10, not 5. Hence, printing 5 contradicts the function’s return statement.
Option 3: 10
This option aligns with the function’s definition: doubleIt(x) returns x * 2. When main calls a = 5 and then prints doubleIt(a), the expression evaluates to 5 * 2, which equals 10. Therefore this matches the observed result of the program.
Option 4: 4
A result of 4 would imply either the function subtracted 1, or performed a different operation like x - 1 or x / something, which is not present in the code. Since doubleIt multiplies by 2, obtaining 4 would require input 2, which is not the value being passed (a is 5). Thus this option is inconsistent with the program’s logic.
In summary, the only choice that coherently reflects the function’s defined operation and the values used in main is 10, since the code computes 5 * 2 and prints that result. The other options fail to account for the actual multiplication by 2 performed by doubleIt and the initial value of a.
