Check if the square root of the number is an integer
If yes, then it is a perfect square
Smart pointers in C++ are objects that act like pointers but provide automatic memory management.
Smart pointers help prevent memory leaks by automatically managing memory allocation and deallocation.
Examples include unique_ptr, shared_ptr, and weak_ptr.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to prevent circular references.
Mutual exclusion is a concept in concurrent programming where only one thread can access a shared resource at a time.
Ensures that only one thread can access a critical section of code at a time
Prevents race conditions and data corruption
Commonly implemented using locks, semaphores, or mutexes
Example: Using a mutex to protect a shared variable in a multi-threaded application
Implementing multithreading involves creating and managing multiple threads to execute tasks concurrently.
Identify the tasks that can be executed concurrently
Create and manage multiple threads to execute these tasks simultaneously
Use synchronization techniques like locks and semaphores to prevent race conditions
Handle communication and coordination between threads
Consider thread safety and resource sharing issues
