array::swap

Swaps the contents of two arrays.

void swap(array& right);

Parameters

• right
  Array to swap contents with.

Remarks

The member function swaps the controlled sequences between *this and right. It performs a number of element assignments and constructor calls proportional to N.

Example

 

// std_tr1__array__array_swap.cpp 
// compile with: /EHsc 
#include <array> 
#include <iostream> 
 
typedef std::array<int, 4> Myarray; 
int main() 
    { 
    Myarray c0 = {0, 1, 2, 3}; 
 
// display contents " 0 1 2 3" 
    for (Myarray::const_iterator it = c0.begin(); 
        it != c0.end(); ++it) 
        std::cout << " " << *it; 
    std::cout << std::endl; 
 
    Myarray c1 = {4, 5, 6, 7}; 
    c0.swap(c1); 
 
// display swapped contents " 4 5 6 7" 
    for (Myarray::const_iterator it = c0.begin(); 
        it != c0.end(); ++it) 
        std::cout << " " << *it; 
    std::cout << std::endl; 
 
    swap(c0, c1); 
 
// display swapped contents " 0 1 2 3" 
    for (Myarray::const_iterator it = c0.begin(); 
        it != c0.end(); ++it) 
        std::cout << " " << *it; 
    std::cout << std::endl; 
 
    return (0); 
    }
