The content of this article mainly explains "what is the method of C++ multithreading to get the return value", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "C++ multi-threaded method to get the return value is what" it!

Let's use an example to illustrate how to implement this requirement. Calculate the value of (axib) / (xroomy) with multiple threads

There are two ways, respectively

1. Traditional method: sharing pointers between threads

# include#include#include#includeusing namespace std; void func2 (int x, int yjournal intt * ans) {* ans= x int;} int main () {/ / calculate (aplb) / (xmapy) / / with three threads, one thread calculates aquib, the other thread calculates xroomy int a, b, x, y; a = 10, b = 8, x = 2, y = 4; int* sum1 = new int (0); int* sum2 = new int (0) Thread T1 (func2, a, b, sum1); t1.join (); thread T2 (func2, x, y, sum2); t2.join (); cout
