Introduction to Threading and Concurrency in C++
Multithreading allows the execution of multiple threads concurrently, providing better performance and responsiveness in certain scenarios. In C++, threading is achieved using the “ header from the Standard Template Library (STL).
Key Concepts:
- Thread: A sequence of instructions executed independently. Threads within the same process share the same memory space.- Concurrency: The execution of multiple threads that can run independently and make progress concurrently.- Mutex (Mutual Exclusion): Mechanism to prevent multiple threads from accessing shared resources simultaneously, avoiding conflicts. ## Exercise: Write a Multi- Threaded Program
Let’s implement a simple multi-threaded program that calculates the sum of numbers concurrently. We’ll use two threads to calculate the sum of numbers from 1 to 50 and 51 to 100, and then combine the results.
Conclusion
Feel free to modify the program or experiment with different multithreading concepts. This exercise will provide hands-on experience with multithreading in C++. From mastering input/output streams to seamlessly managing file operations, these skills are integral to crafting robust and efficient applications. Happy coding!
