Solution
The correct answer is 010100.
Here's the step by step explanation:
The given C code is a recursive function that prints the binary representation of a number.
- The function is called with N=20.
- It checks if N is 0, if not it prints the remainder of N divided by 2, which gives the last digit of the binary representation.
- Then it calls itself with N divided by 2, effectively removing the last digit of the binary representation.
- This process repeats until N becomes 0, at which point the function returns without printing anything.
The binary representation of 20 is 10100. However, because the function prints the digits in reverse order (it prints the remainder of N divided by 2 before making the recursive call), the output is the reverse of this, which is 010100.
