create n threads cpp
To create n threads in C++, you can use the following steps:
Include the necessary header file for threading in C++:
cpp #include <thread>
Define a function that each thread will execute. This function should take any necessary parameters and return void. For example:
cpp void threadFunction(int threadID) { // Thread logic goes here }
In the main function, create n threads using a loop and specify the function to be executed by each thread along with any required arguments:
cpp int main() { int n = 5; // Number of threads to create std::thread threads[n]; for (int i = 0; i < n; ++i) { threads[i] = std::thread(threadFunction, i); } }
Join the threads in the main function to ensure that the program waits for all threads to complete before exiting:
cpp for (int i = 0; i < n; ++i) { threads[i].join(); }
Compile and run the program to see the multiple threads in action.
These steps will help you create n threads in C++ and execute the specified function concurrently.
