Creates a std::pair object, deducing the target type from the types of arguments.
[edit] Parameters x, y - the values to construct the pair from [edit] Return value [edit] Example#include <functional>
#include <iostream>
#include <utility>
int main()
{
int n = 1;
int a[5] = {1, 2, 3, 4, 5};
// build a pair from two ints
auto p1 = std::make_pair(n, a[1]);
std::cout << "The value of p1 is "
<< '(' << p1.first << ", " << p1.second << ")\n";
// build a pair from a reference to int and an array (decayed to pointer)
auto p2 = std::make_pair(std::ref(n), a);
n = 7;
std::cout << "The value of p2 is "
<< '(' << p2.first << ", " << *(p2.second + 2) << ")\n";
}
Output:
The value of p1 is (1, 2) The value of p2 is (7, 3)[edit] Defect reports
