How do I use parameters in C++ thread library?

Can you explain how to use parameters with the C++ thread library?

Sure! In C++, you can pass parameters to a thread function by using std::thread. You can pass them directly as arguments.

Can you show me a code example?

Absolutely! Here's a simple example:

#include <iostream>
#include <thread>

void printNumber(int n) {
    std::cout << "Number: " << n << std::endl;
}

int main() {
    std::thread t(printNumber, 5);
    t.join();
    return 0;
}

This creates a thread that runs the printNumber function with 5 as the parameter.

What happens if I want to pass multiple parameters?

You can pass multiple parameters by simply adding them after the function name in the std::thread constructor. For example:

void printNumbers(int a, int b) {
    std::cout << "Numbers: " << a << " and " << b << std::endl;
}

std::thread t(printNumbers, 5, 10);

This will pass both 5 and 10 to the printNumbers function.

Are there any limitations I should be aware of?

Yes, one limitation is that the parameters are copied into the thread. If you want to pass large objects, consider using references or pointers, but be cautious about their lifetime.
