In the following example, we are going to use the std::tie() with the forward_as_tuple() function.Open Compiler #include <tuple> #include <iostream> int main() { int x = 1; float y = 0.01; std::tie(x, y) = std::forward_as_tuple(x, y); std::cout << x << ", " <<...
Example Run this code #include <iostream>#include #include <tuple>#include <string>intmain(){std::map<int,std::string>m;m.emplace(std::piecewise_construct, std::forward_as_tuple(10), std::forward_as_tuple(20,'a'));std::cout<<"m[10] = "<<m[10]<<'\n';// The following...
