What is the output of the following code: int v() { int m=0; return m++; } int main() { cout<

  1. 1

  2. 0

  3. Code cannot compile

  4. None of the Above


Correct Option: B

AI Explanation

To determine the output of the given code, let's analyze the code step by step:

  1. The function int v() is defined, which returns an integer value.
  2. Inside the function v(), a variable m is declared and initialized to 0.
  3. The statement return m++; is used to return the value of m and then increment it by 1. However, the postfix increment operator (++) returns the original value of m before incrementing it.
  4. The main() function is defined.
  5. The output statement cout &lt;&lt; v(); is used to call the v() function and print its return value.

Now, let's go through each option to determine the correct output:

Option A) 1 - This option is incorrect because the postfix increment operator (m++) returns the original value of m before incrementing it. Therefore, the value returned by v() will be 0.

Option B) 0 - This option is correct because the return statement return m++; returns the initial value of m, which is 0.

Option C) Code cannot compile - This option is incorrect because the code provided is syntactically correct and will compile without any errors.

Option D) None of the Above - This option is incorrect because the correct answer is Option B) 0.

Therefore, the correct answer is Option B) 0.
