Q1. Cpp pointers explain smart pointers
Ans. 
Smart pointers in C++ provide automatic memory management and help prevent memory leaks.

Q1. What are flip flops and latches
Ans. 
Flip flops and latches are sequential logic circuits used in digital electronics to store and transfer data.
• Flip flops are clocked circuits that store one bit of data, while latches are level-sensitive circuits that store data as long as the enable signal is active.

• Flip flops are edge-triggered, meaning they change state on a clock edge, while latches are level-triggered, changing state as long as the enable signal is ...read more
