cause problems or even cause the entire program to crash. If the program can be divided into different independent tasks and multithreading is used, even if a part of the task fails, it will not affect other tasks and will not cause the whole program to crash. There is no doubt that writing a multi-threaded program gives you a powerful tool to drive a non-multi-threaded program, but multithreading may also become a burden or a huge cost. Improper use
