Challenge Problems
Push your limits with advanced challenges
In a scenario, you are developing a function that can handle addition of numbers based on their type (signed/unsigned). What precautions should your function take regarding overflow and carry flags?
💡 Hint: Think about logic flows that differentiate signed from unsigned operations.
You performed the addition of two large 4-bit numbers, 15 and 1 in unsigned arithmetic. Explain what happens and how it correlates to carry and subsequent calculations.
💡 Hint: What do you know about maximum values in binary dynamic?
