What are the advantages and disadvantages of using multithreading in programming?.

Advantages of multithreading:

• Increased performance through parallel execution of tasks, especially on multi-core processors.
• Improved responsiveness of applications (for example, the UI remains active during background operations).
• Ability to efficiently utilize resources, for example, waiting for input/output in one thread does not block others.

Disadvantages:

• Development and debugging complexity due to the need for synchronization of access to shared data (risk of races, deadlocks).
• Increased resource consumption (creation and context switching of threads).
• Does not always lead to acceleration, especially if tasks are highly dependent on each other or resource-constrained.

Example: in C++, you can use std::thread to run parallel tasks, but you need to carefully work with shared variables using mutexes.
