Step 4: Divide 5 by 2. If you want to transform a number into another number (not number to string of characters), and you can do with a small range (0 to 1023 for implementations with 32-bit integers), you don't need to add char* to the solution, HalosGhost suggested to compact the code into a single line. Still undefined behavior. You can write a binary literal directly in your code like this: Link-only answers can become invalid if the linked page changes.
